No Audio Output Device
Hello,
I just installed Windows Vista Business RTM...
Everything works well, except for the sound... the sound device is installed correctly, but I don't have any sound!
When I put my mouse on the sound icon (right under, next to the time) I get the following message:
No Audio Output Device is installed
I use a Notebook from HP (nx9420).
Could somebody please help me with this issue?
Thanks!!
Best regards,
Geoffrey Beulque

I have the same problen on an Intel 975BX board. I have check drivers and all seems okay.
Does anyone have a solution???
- i have the same issue, running a ACPI x86 motherboard, and my audio worked completely fine on Windows XP, never once had an issue and i now installed (a clean install) Windows Vista Basic and get the "no audio output device installed". my speakers are plugged in and everything, this is really really annoying and i hope someone comes up with a solution soon, it sucks trying to game or listen to music without sound =)
I have recently bought a new Sony VAIO (Laptop) VGN-FE41E. After I expericenced some windows problems I have upgraded the system software (Windows Vista Home Premium OEMAct). Then my computer fell silent. When I hover over the sound icon next to the clock. (bottom right hand corner) I get the message "No Audio Output Device is installed." Before I upgraded my Vista the device worked properly-previously I was using the same system software.
To solve the problem I have tried the following:
1- In the control panel> Harware and sound > sound, it is indicated that “No audio devices are installed”
2- In the control panel> Device manager, under Sound, video and game conrollers I have found SigmaTel High Definition Audio Codec. I have tried to update the driver of this device by right clicking. I was notified that “Windows has determined the driver software for your device is up to date”
3- Afterwards I disabled and enabled the device. It did not solve the problem.
4- Afterwards I uninstalled the device and reinsalled it again in Device manager. It did not work.
5- I also visited the driver databse website ( http://www.driversdb.com/device.php?id=73047 ) no driver is offered for this product for windows Vista (For other system software they do).
6- VAIO website does also not offer drivers for this product.
Can anyone help me to solve this problem?

- I have had the same experience with a new Vaio FE41Z. It worked fine with Vista Home Premium, then I upgraded to Ultimate and I get the same messages as you (No audio input or output devices installed).
- Hi,
I too have no sound. Vista thinks there is a High Definition Audio Device (in Device Manager) and that its driver is working ok. But when you go to the Sound panel on the Playback panel it shows an icon for Headphones and says High Definition Audio device Not plugged in (and plugging headphones in doesnt change things!).
Hp Pavillion t3355.uk ASUS P5LP-LE motherboard, with Relatek 882 , Vista Ultimate. - I was able to solve the problem by rolling back to the preinstalled factory state by using Vaio system recovery tool.
For an alternative solution see
http://www.community.windowsreinstall.com/index.php?showtopic=110&st=0&gopid=408&
Try going here:
I found that the Realtek AC'97 Audio Codecs corrected every sound issue that I have had with Vista. Uninstall any existing sound drivers before downloading this software. The install is straight forward. What is the worst that can happen? You don't have any sound.
I believe I have a solution.
Scenario: I bought a new Sony Vaio on Sunday, and upgraded Vista to Vista Ultimate yesterday. Immediately the sound system fell silent. After following other suggestions I checked the updates I had installed following the upgrade to Ultimate. Windows and discovered that Update for Windows Vista (KB929685) says:
"Install this update to address an issue that may prevent high-definition audio devices from initializing after resuming the system from a sleep or hibernation state."
I had put the PC to sleep around that point.
Here is what I did next:
In Conrol Panel -> System -> Select the Device Manager and find the Sound entry. Expand it. Click the entry for High Definiton Audio Device with the right mouse button. Uninstall it and the software too (check the box).
Now put the PC to sleep. When it restarts it will reinstall the Audio device. Meantime the update above (KB929685) seemed to have kicked in and PRESTO - sound again!
Worked for me. Good luck.

- I have to agree with KenCrash, I tried hard to find compatible drivers for my Soundblaster live/audigy but Creative's website says they are not even planning on updating Live, not sure about Audigy. I have heard their upper XI models generally work with Vista. I fixed by simply re-enabling my onboard sound card of C-media and downloading the latest AC 97. It seems AC97 is becoming very popular because nothing else works with Vista, least without buying a new soundcard.
Thanks man!
Worked for me too as i experienced precisely the same after upgrade to my new FE41Z!
I have to say that any of the solutions in this forum or other worked for me... :( not even the realtec drivers... but now im listening a good song from my speakers...
I have a HP pavillion dv 1000 notebook...
I went to the HP web page to find support & drivers for WV. , I found a link to download a program from HP to update drivers for WV but it didnt work... so...
simply I contact HP... I choose chat online with a Technician.. by the way her name was Pearl. mmmm.. and she gave me the links to upgrade my Conexant High - Definition Audio Driver... then my speakers sound again!!!
what does this mean?
they have all the drivers for WV u need... just we need to ask for them...
I hope this will be helpful for all of you.
Yep, I've had the same experience.
Bought the VAIO with VISTA Home premium and all was ok, upgraded to Vista Ultimate and lost the sound. "No Audio Output device is installed" is the message I see when I hover my mouse over the speaker icon in the system tray.
Has anyone found a solution?
Dear Geoffrey Beulque
See the following link for some alternatives
http://club.vaio.sony.co.uk/clubvaio/gb/en/forum/viewthread?thread=39831
after spending hours researching and trying to fix exactly the same problem with the audio device, I want to thank "copperminecottage" for the information, and want to share my experience fixing this problem:
I use the SigmaTel High Def. CODEC audio device on my DELL laptop with Vista OS. After uninstall the driver, and reboot to automatically reinstall it, the audio still did not work. Amazingly, without doing much other, after put the system in Hibernate mode and come back, the auto worked.
Don't have time to figure it out why, but this worked for me - Don't forget to Hibernate the system & "wake" it up first before saying it's still not working.
Good luck.
-Cello1
p.s. Though I have to say that I am having quite some issues with applications & drivers not compatible with the new OS - Vista yet. Guess it will take a little while for applications working out the solution for Vista.
Coppermine you beauty... Searched for hours for an answer before i found your post! Your solution worked like a dream, now i can get back to listening to Mcfly!
(I have Vista Home Premium by the way)
Thanks again.
- THANKS SO MUCH!! It worked great! Did this on a Gateway laptop, just installed Vista yesterday and NO SOUND. Thanks for the info.

It worked!
I was getting really frustrated. I just bought a DELL INSPIRON 1501 and decided to upgrade to the Vista Premium. Imediatly after install there was no sound. What a nightmare! I found this web page and followed your instructions. Sound is up and running.
Thanks Alot!

- Christ, I am at my wits end and hope to God that someone can help me.
Like everyone else I brought a copy of Vista (Home Prem) and excitedly installed it, only to find that No Audio Output Device was Installed. I called up Microsoft, but was told to essentially go and jump because my version is an OEM. I called up HP to see if they could help with their HD, but after twenty minutes with an Indian fella in an Outsourced office, I was informed that HP may have an updated driver in a couple months (if I'm lucky).
A couple months with no sound is unacceptable... a couple days with no sound is unacceptable.
Now, I've tried uninstalling and reinstalling with no luck. I followed KenCrash's suggestion and I downloaded the Realtek AC'97 Audio Codecs and tried installing them, but every time I tried to do so a Microsoft warning about the program not having a valid (my word) digital signature kept coming up, and no matter how many times I clicked Install Anyway, the installation just wouldn't move.
Finally after starting and stopping four times, the Program announced that it was for 64bit Vista's only. So, I don't know what to do. Please, i hope someone can help me.
My computer is a Compaq Presario v5120 Laptop.
I have a Intel DUO chip (T200 @ 1.66 Ghz if I'm ready this right)
0.99 GB of RAM
Mobile Intel(R) 945M Express`Chipset Controller 0
Vista Home Prem (32 bit version) try this'
Go to the Control Panel
Then Go to Administrative Tools
Then Go to Component Services
Then go to Local Services and expand the window
Then scroll down to Windows Audio change it to automatic and/or start it (under status)
You may want to look at some of the other things there and click on their description to see if you want the automatic instead of manual option like the Plug and Play and whatever controls your wireless connections
- Thank you copperminecottage. Your solution worked for me also; it's nice to be able to hear again!
I have a dell xps 410 and after updating to ultimate I had the same problem. I installed the KB929685, uninstalled the Sigma driver, rebooted and it worked !!!!!!!!!!
- I tried this fix on my Dell INSPITON E1505, and it did work. Only problem is it automatically installed a Microsoft driver, and the sound does work, but is much inferior to the quality afforded by the Sigma Tel driver. Like not in Hi-Fi at all, but it does make noise! Will settle for this until a new driver is offered that has some decent sound quality. Thanks for the uninstall concept. It does work!
- BIG thanks to copperminecottage...worked a treat...only a couple of days without sound had me going spare! Thanks again well done
Go to Start and type: services.msc
Scroll down the list of services until you find Windows Audio
Open up Windows Audio by double clicking
Make sure it is running, if not, click on Start
Note: This worked for me. I just installed MS Office 2007 and the problem showed up right after the installation. It has been a chronic problem so I hope this is the final fix. I hope this tip helps you.

- It worked for me as well. Thanks so much for posting what you did because I was trying everything and nothing was working, it would keep on saying " no output audio device installed ". Thanks again!!
Thanks!!!!!!!!!!!!!!!!!!\
I tried it and it worked!
Thank You =)
Wow......thanks alot COPPERMINECOTTAGE, for a moment I though I was going crazy, I tried do fix the problem by my self but I would never though of doing what you suggested. I am so happy, now I can listen to my music and feel alive again. I personally apreciated your help. @nn!e
- This solution worked for me as well. Thanks Copperminecottage!
- Wanted to thank you.... installed Vista no problem.. tried to load McAfee - crashed the system & had to take the system into the service provider to get the programs loaded... came home - no screen saver.. loaded Windows update and took care of that problem. Next day, no sound.. very aggravating for my nervy husband. Came home today to find that he had spent hours trying to fix the problem with no success... Found your blog and had the problem fixed in 4 minutes - thanx for making me win the bet and prove that I am the better computer person (coz of you). He owes me dinner!! For all reading this post, THIS IS THE SOLUTION!!!!!
Ok someone please help!
Also have the same problem, but have tried every solution people offer but to no avail. Both speakers and headphone don't work. I've tried to install the update on Microsoft's website and it says it does not apply to me. Have both restarted and hibernated after uninstalling the sound driver and nothing changes. I'm pretty sure (although starting to wonder if I'm being delusional as i haven't seen it since) that Microsoft will issue a new update soon, but it is still going through the testing stages. If anyone can divert me to that, it would be most appreciated!
Does anyone have any more ideas as to how to fix this problem?

The update by microsoft:
Windows Vista (KB929685) says:
"Install this update to address an issue that may prevent high-definition audio devices from initializing after resuming the system from a sleep or hibernation state."
This update don't work for my Compaq Presario V3136. This is a dump issue by microsoft drivers! Microsoft update cannot resolved this issue after hibernate. I tried various means wihtout much success.
Scenario:
Compaq Presario V3136 notebook upgrade from XP to Windows Vista Home Premium. Windows Vista Home Premium initial sound no problems. However, when the notebook wakes up from Hibernate mood, there is no sound from the notebook even though the speaker/ sound icon still shows the sound fluctuating when I test a MP3 sound but no sound.
1. Tried uninstalling the high definition audio and rescan in system/devices to reinstall the driver. It works on the spot. However when you put it back to Hibernate and wakes up again, NO SOUND!!. Even though the windows update already update the KB929685. CRAB!
2. Tried coppermine suggestion, same thing happens as step 1, NO SOUND WHEN WAKES UP FROM HIBERNATE!!
3. This is serious as there is no known solution to this problem. It seems stupid to uninstall and reinstall the driver everytime the system wakes up from Hibernate.
4. I even tried by going to administrative tools, services, stop and start the windows audio services, still NO SOUND!
Is Microsoft programmers serious about fixing this issue?

I too have a Sony Vaio FE41S, and installed the Vista upgrade, I took copperminecottage advice and it worked, thank you so much I would never have been that brave to do that, its great to have sound back, and it was sorted in seconds, thanks again
I bought a DELL C521 and it works great... but then I purchased a program that uses the winhlp32.exe to display that programs help files.
Well I went to the MS website and tried to download this file and the page kept freezing up when I would select "continue - Validation required.
So I thought "I will reinstall Vista Home Premium" to help fix this problem and it did work, the webpage did not freeze up again.
Well after the re-install I noticed that my sound mixer would not recongnized my sound card. "No output audio device is installed".
I must have re-installed the video driver 10 times then went looking for an answer for this problem. Found your solution and it worked.
I put my computer to sleep then woke it up and now I have my sound back on new computer. thanks copperminecottage!

I got an Acer aspire T650, i recently upgraded from Windows XP to Windows Vista Home Premium, However now i have upgraded i have no sound, i cannot play music in Windows Media Player it says there are no sound devices installed, the same with the system tray it says 'no sound output devices installed', Under hardware and devices > sound, video and game controllers it shows; Fly DVB-T Hybrid and underneath that it shows High definition audio device but with a yellow symbol and on it's properties it says this device cannot start (code 10).
I never had any problems before upgrading and i have 2 sets of speakers, Acer and I.t Works neither of them work, i did have realtek high def audio in my system tray when i had XP and when i upgraded too but now that seems to have disappered from my computer the same with the master volume in system tray it had no X on it but now it does (obviously meaning no device installed). but all my speakers are plugged in, there no updates on windows to make them work i have all current updates. What to do? i don't know!!!!! I followed copperminecottage instructions and indeed it did as it said but then said 'device installation failed!' it didn't say why.
Thank you so much! You are a genius - this absolutely worked for me. I have been setting up my brand new Gateway laptop, and like several people who mentioned upgrading to Ultimate, I had no sound. This is great - I have sound! I was so worried something was really wrong with my brand new computer. Appreciate the help.

Hey, same thing with me, i just installed vista ulitmate and lost my sound, all drivers show installed, but icon on front page has red x and says no audio output. I thought i was going nuts and have spent now 5 hrs trying to solve this myself. ran across this site by accident. i'll read on and see if htere is a fix to this...
whew!!!

- I had the same problem with my hp. Goto http://www.realtek.com.tw/downloads/ and have a look at the high def there will be a driver for vista. Downloads and install that. It will remove your old drivers by itself. And you will have sound
copperminecottage you're a genius! I talked to Dell about my upgrade from Vista Home Basic to Vista Business on my c521 and it knocked out my sound. They went through so many steps (very helpful) but in the end wanted me to contact MS.
I'm glad I did some searching before calling them. Your fix helped! Thank you SO much for posting it

- hi how did u solve ur problem. i done the same thing and my sound was gone too can you help me please
- didn't loose audio until downloaded RealTek Vista_r165 the first time. tried uninstall/sleep shown in string above, but didn't get results until I downloaded Vista_R165 (executable) a second time. After restart, the red X had disappeared. Still had to go in and change default speakers to the ones I had hooked up...but they're working fine now.

go to this link u will have an answer After many days and without the support of Microsoft and my PC vendor i fixed the problem.
PROBLEM:
- Acer Travelmate 3000: "no Audio Output Device" message.
- the Acer website for Vista redir to a Realtek driver.... bullshit...
at the end, trying to use my XP drivers i discovered it was a SigmaTel and NOT a Realtek driver that i had to search.
Sigmatel and Acer websites don't provide any drivers, finally i found it on Packard Bell website:
http://support.packardbell.com/es/item/index.php?pn=PB62Q00304&t=2007
download Sigmatel High Definition Drivers.
launch the installation software, it will break before complete the installation but it will save in your c:\drivers folder the driver you need...
now install it manually from Device Manager.
... a little tricky but it works, i hope it can help many Acer users that i read had my same problem.
Bye.
All I did was a roll back for my audio divice and now it works again.
How I did was:
Open control panel, then divce manager, open sound, double click on the divce you have for sound. (with windows vista might be: Sigma Tel High Definition Audio CODEC...and open, then go to Drives tabs on top..then select "roll back".
Hope this helps. Have a good day.

- Well I simply went control panel-device manager-sound- delete sigmatel audio tec -the pc will automatically install a new audio output device that is compatible with windows vista.---I hope it could help some of you!!!!!Chow chow
- hey thankyou so very very much. your advice worked a treat - i thought i was going to be lost without music, but yes, thank so very very much
- yes that did the job, thank you very much!
- I cant roll back
- I have upgraded to vista ultimate and since then I have had the same problem. I am not able to select the option for roll back. What can I do?
Thanks JJS41. I was able to fix my brand new HP Pavillion dv9210 sound problem with your precise explanation of the fix. Glad to have people like you around to trouble-shoot what Microsoft hasn't fixed.
girlsaylor
Thank you so very much!
The funny thing, for me, is that I went into device manager and uninstalled the driver the other day I but didn't check the check box. When I rebooted and still had no sound, I just kept trying other things and googling the error message. I really thought that uninstalling the software was irrelevant to the problem at hand. Goes to show the saying is true... never assume..
Again, thank you very much copperminecottage and everyone else that said copperminecottage's solution worked. Had it not been for all your posts, I would still be troubleshooting and debating on calling tech support.
Thanks again!

I opened control panel, went to device maneger, and clicked on my high definition audio controller (the one I use) and i tried rolling back but it wont let me click on roll over driver and to the right of it it says ìf the device fails after updating the driver roll back to previously installed driver. so i tried searching for updates, and there isnt any, and i still cant click on roll over driver, what do I dogo through the uninstall process for the "sigma tel high definition audio CODEC", whether it be through the control panel uninstall software, or device manager bring up audio driver and uninstall.
Then reboot the computer, windows vista will find and reinstall automaticaly.
Could someone help me? I just reformated my machine and I don!t have no sound whatsoever
Thanks a million

After reading your posted message, I tried hibernating my laptop and it reinstalled the audio driver automatic!!! Thanks for help for trouble shooting.Thanks for your suggestion. I removed the driver and re-booted. The computer recognized the problem and installed a new driver. Now the audio system is working.
Wow you just totally saved me from throwing five laptops out a window. I have spent five hours today trying to get this ONE stupid sound driver working so I could flash several machines... I googled and googled and googled... Thanks, good find!
And just a beef I discovered along the way - HP / Compaq has the WORST product support / driver download site I've ever encountered... don't look to them for any assistance on Vista compatibility. I'm not sure what I'm going to do when the users of these new machines start plugging them into HP printers

hey everybodym, i cant mess up with this problem
i am operating on a 32bit system and i did the followings:
firstly i uninstalled my high definition driver and then windows tried reinstalled it automaticaly
at the end of the update it notifies me that it had failed
i also tried to install another windows update KDB....(cant remind) and it also failed because it was available only for 64 and 86 bit versions
can somebody please help me? i am need sound on my comp immediately because my job depends on it
And if there is no solution should i buy another new sound card?if so which one is the best for my situation?
I'm experiencing the same problem. Where do I find the answer to this problem that you posted?
What I had to do was put the computer in hibernation mode. Once you take it out of hibernation mode it will reinstall the audio driver.

As I am not in any way a genius at this, is this the only way you found to get the device back, restoring default settings? I needed to upgrade to Ultimate from Hoem Premium. It seems as though reverting to the factory settings would default the issue back to home premium.
Wow! Copperminecottage (p2) This worked for me! Fixed the problem very easily. Thank you very much.after you diabled the device in # 2 you then need to put your computer in hibernation mode or sleep mode. When you bring it back up it should work ok, if not try restoring your computer to the point of when it was working ok.
THANKS A LOT man. It worked for me too.
Thanks copperminecottage, that worked for me. I was getting a little frustated there. I recommend doing this for anyone that has a sound issue when you upgrade.
I have an Sony Vaio PCV-RS220 and I reinstalled to an upgraded version of Windows XP (Media Center). All of the drivers I downloaded from Sony have worked EXCEPT for the sound!!! I tried copperminecottages method, which was on page 1, not 2, and it didn't work either. Im not upgrading to winodws vista, just windows xp 2005. PLEASE HELP!!!!! ILL TRY ANYTHING AT THIS POINT!!!
For anyone that upgraded from XP to vista and lost sound and all you get is a message that says "No audio output device is installed", you might wanna try to download the windows update kb937077 that says "Install this update to resolve an issue where a high definition audio device (HDA) may no longer work after a system running Windows Vista returns from sleep, or hibernation and then restarts.", after installing it, uninstall your audio driver and put your computer to hibernation, wake it up again and it should install it automatically, windows is going to install the audio driver that came with windows vista if this does not help it means that your audio won't work with the driver provided in the windows vista upgrade, so you go to plan B:
Go to the website of your computer's brand (HP, sony, dell, etc.) and look for the audio driver that came with your computer when you had XP, with your computer model number you should be able to find it and install it, even though you're now running vista it should work, and you'll get your sound back.How can i fix it
Thanks. Had the same problem after removing a user due to a virus. I had never been to the divice manager before. Once there, I worked it out and downloaded what I needed for the sound to work again.hi my computer have a problem now..so ..sound not come out ..why was that ? the computer said no audio output device..how can I do this problem ..
this computer always give me a problem ..compaq is not good .. I never buy later ..also windows vista ..really really not good... alway have problem ..
please help me ..
Seems like loads of people have the same problem! Many Sony Vaio's though, and only few Acer's

I have about 3 months old Acer Aspire 9423 notebook (Intel High Definition Audio, Vista Home Premium, Centrino Duo etc. etc). Sounds worked well for about 2 months until they just suddenly stopped working without me doing any upgrades or any changes to the system. I don't understand this, since the auto updates Vista has installed don't seem to be the cause to this issue. It's not sleep or hibernation that has anything to do with it. Doesn't matter how I try, the audio stays unfound. Can't be my sound card since so many other pc users encounter this from different manufacturers.Edit 12.11.2007: Forgot to mention, I was yet again for the millionth time trying to get the sound card work when I installed or uninstalled the Realtek drivers. Said it failed and after that the sounds worked just fine on my profile. After switching to an other one the next day, the soundware were gone again. I mean it can't be the card?
I've googled over the tech support forums randomly for about 3 weeks now. Still no solution. For 3 weeks the sound has been gone (I AM GOING MAD) and I haven't had the determination to try all the time. I was going to send it to warranty maintenance, but changed my mind after hearing all of you guys having the same problem on different platforms.
How can this be? IT HAS BEEN GOING ON FOR OVER 6 MONTHS NOW (for random Vista users)! Is Microsoft going to do something about this? Whose responsibility is it? Acer's? Realtek's? The KB updates are worth nothing. I have them all, doesn't help.
I tried all the updates recommended, no change what so ever. I'm so fed up with this, spent like 50 hours on this and still no change. Others can atleast see "Sound, video" etc. on Device Manager. I've got nothing on there either. Anything that has anything to do with sound cannot be found on dev mangr.
And yes, I also tried putting the audio up from the local services. Was started and automatic, doesn't make a difference..
I've tried:
- Restore points
- Re-installations
- Registry cleaning and other registry "tricks"
- Driver updates (chipset manufacturer and Acer)
- All the KB's
- All the other methods described on this thread- Check it from BIOS
Edit 12.11.2007:
Tried Ubuntu Linux, didn't find it either, but that was running live from CD. I called Acer, they want me to send it to service maintenance, but I need it all the time, I cannot just send it off to random people to deal with it
I wish customer tech support people could help advanced users, with their knowlegde and advice, but instead they just tell you to send it somewhere. Also heard that there is a ghost partition on the PC. I was ondering where 20 gigas of hd space had gone. Only shows 140 of 160. Proper sneaks the people of Acer... How can this be ffs.I deleted hibernation option ages ago, dunno what I was thinking.. I wasn't using it an it was disturbing me cause it screwed up the resolution once when i tried it.. I think I'll just throw this piece of **** out the window. Driving me insane.. Where are all the other Acer users who have this problem?
I had this problem too. I was SO STRESSED about it. THANK YOU SOOO MUCH!!!! I did everything copperminecottage said, and it WORKED. THANK YOU!OK, finally got this one, or at least I do for the 975xbx2 users. This just happened to me, sound was working perfectly on a computer I built with a 975xbx2 board, and vist ultimate loaded. I couldnt figure this thing out for the life of me. Most forums seemed to point towards hibernation, however, I couldnt install the update, it would say my system doesnt qualify. But I do remember that my system went to sleep once and the problem occured shortly thereafter. I also remember that when I was working as a PC tech, that occasionally a notebook computer would go into hibernation, then wouldnt come out. So I tried that approach, turn the computer off, and remove the power cable, then with the power cable removed, press the power button. At this point, youll actually see an LED or two light up (if equipped) or may see one of your fans jolt, this is dumping the capicitors, and any memory. Then reconnect the power cable and turn the machine on. It will go through the finding new devices process, and there it is.For you notebook users, unplug from the wall and remove the main battery, then press the power to dump the caps. The reconnect the battery and power cable (if needed).

copperminecottage, thank you thank you thank you!
I had tried EVERYTHING before this! Even talked to a support person in this chat thing. I had been trying things since last night and earlier today and nothing worked!

what do you recommend doing for this audio problem? i see lots of people found a way to fix this but i can't see the reply to see what they did. thanksHey all,
I just upgraded my vaio notebook from XP to Vista yesterday. I have found many problems with it. I have called Sony Support and some guy, who I could barely understand told me something about him not having drivers and something else about the motherboard. To end the call he said that I should have bought Sony's vista upgrade package. When was I supposed to think about that while in future shop? I gave up with this guy and called Microsoft. They want 79$ to help me with the problem they have caused! Ehh, I think not, I already spent enough on the home premium package you would think they would help for free!
I found a way to fix my "audio output" problem I was having a few ways.
1.
I simply restored my computer to an earlier date. (However I have only had vista a day, so anything I had downloaded and installed for other programs where missing, i.e Norton 360) This opyion may work for others who have just found the problem and have no reason not to restore to a date where your computer worked fine
2.
After i un did my system restore I was back at square one with no sound. I tried this and it worked
Follow these and click on them
-start
-control panel
-Classic view
-system
-device manager
-Sound, video and game controlers (click the little + to expand)
- right click the sound device
- click update driver software
Let this run and there you go you should have sound working again
Now I just have to go find some information on how to get my function keys working again on my keyboard, Find out how to re-install my MS office 2007 and find a way to get my computer to pick up wireless again!
Anyone have any ideas?
By the way, thanks microsoft, you robbing bastardsFor the 975 board do this, turn it off, actull shutdown, NOT HYBERNATE. after it is completely shut off, unplug the power, then press the start button on the front of the computer case and hold it for about 5 seconds. Then plug the power back in and turn it on. You may get the install new devices wizard.Worked like a charm...Thanks!
Audio links have stopped working from my computer. The same links work on other computers. What's wrong?Same thing happened to me.
Go to Control Panel -> Hardware and Sound-> Device Manager -> Sound, video and game controllers.
Expand it. Click the entry for High Definiton Audio Device and right click it with your right mouse button. Uninstall it.
Now put your PC to sleep. And then restart it. When it restarts it will reinstall the Audio Output device.
You are an immortal. I was up half the night trying tech chain solution after solution. Yours worked and the quickest. I can't thank you enought.
Have a wonderful holiday.

Hello,
I just installed Windows Vista Business RTM...
Everything works well, except for the sound... the sound device is installed correctly, but I don't have any sound!

I have the same problem on my HP Pavilion d4990y. Could not getting any help from HP tech support. I tried to uninstall and reinstall the driver. It didn't not work. I have the Creative Xtreme Gamer sound card. What is the solution to take care of this problem? Thanks in advance.CAN U HELP OR KONW WHAT TWO DO FOR SOUND BACK NOW THE PC ?
For all who have a Sony Vaio PC and upgrade to Vista Ultimate you will lose your sound so I thought Id lend yall a hand and tell yall how to fix it. If your pc is a PCV- type or is a PCV-RZ14G you probably have the Soundmax Integrated Digital Audio driver. What I did was went to the sony website and put in my sony computer which was PCV-RZ14G and went to the original drivers area. The new driver that was listed there was a Yamaha driver. I downloaded it and installed it but when I ran the install it said that it was only for xp, shortly after vista alerted me that the driver was probably installed incorrectly. So i chose the option to reinstall using recommended settings and it pulled up the installer and installed the driver, then I was prompted to restart my computer so i did and after it restarted the sound magically worked! I hope this helps out some people with Sony's out there.
I have Windows Vista Home Premium on a Gateway computer. After running my Operating System Disk, I had no sound. I contacted Gateway and they sent me a detailed e-mail on how to delete the corruped Sigma Tel file and how to reinstall a new driver. It worked great. I have their e-mail if it would help.I fixed mine.
Go to Control Panel
Open Device Manager
Go down to "Sound, video and game controllers"
I had the "Conexant High Defintion SmartAudio HD2" option
I clicked on that
It said that it was disabled
I enabled it
And my sound was back to normal
i hear ya!this industry is too greedy! my computer manufacturer cant help unless i pay 2.79 per minute for their junky upgrade cd! i need help also.audio device driver has become corrupted and needs to be uninstalled.gbeulque wrote: Hello,

you need to copy this link ftp://ftp.hp.com/pub/softpaq/sp35501-36000/sp35684.exe and click run... uninstall your current driver in the device manager in the control panel prior to running this link...
It will say failed a few times when installing, but once complete, it will be successful with sound... i just resolved this problem with HP on the phone!
Good luck!
thanks this worked straight away
Well i have the same problem, but i have a selfmade computer with a Creative Xtream Gamer soundcard and a Asus PB5 motherboard... any ideas?This fix actualy worked. The only thing I did diffrently was respart my computer, but it did just like you said. When it restarts it automaticaly updated.
Thanks!We have had the same problem with the sound, when we up graded from Vista Basic to Premium that's when the problem started. I spent the best part of a week going back and forth with Acer (Aspire) Computers and Microsoft trying to fix the problem. With NO results. Thanks for the site we will give it a try.

copperminecottage, thanks a million buddy!! I have spent 4hrs trying to fix this #%#! and finally got it done.
ADVICE: you might need to perfom the procudure twice as for the first time had no effect. But it def works!THANK YOU SO MUCH COPPERMINECOTTAGE!
I have a Gateway Laptop which uses SigmaTel Audio drivers. After I upgraded from XP to Vista, I saw the X over my taskbar volume icon, but I knew the drivers were installed. I tried your suggestion and it absolutely worked!
(1) Uninstall the High Definition Sound entry & software (check the box)
(2) Put the computer to sleep, and
(3) wake it back up! THAT'S IT!
It didnt even take one minute!please help me i have speakers but no audio an my computer what can i do seriously i need help
yeaaaahhhh man, cheers, followed both solutions and well yeah my sounds back, but i'm thinking it had more to do with this one above though
cheers
Thanks Copperminecottage,
I followed your tip and it works fine.
Good on you. It was so simple so solve but I was looking all over the place for high tech solutions.
FabHi What is the solution?I'm having this same problem. Where did you find the RealTek Vista_r165 software?
where do i put the check for the box cuz i cant find it
Thank you so much COPPERMINECOTTAGE for such wonderful solution to this problem. I had this problem with my Sony Vaio VGN-CR35G and I was lucky to have found this forum!
I had this same problem after I installed SilverLight software for Vista on my Dell Inspiron Laptop (E1505/6400). After searcing several different websites and not having any luck getting sound back on my computer I finally found a sight that worked. Check out the following link...worked for me; hope it does for you too!

I'm glad I did some searching before calling them. Your fix helped! Thank you SO much for posting it
*** here's the e-mail I just sent the tech guy at my workplace ***
See http://www.crn.com/software/207500472.
This just happened to me (I listened to the automatic Windows Update and installed this optional update) - and I need to use my computer's audio to listen to watch and listen to [censored] DVDs for the [censored] project.
Vista people, if they haven't already got this update, really want to avoid getting it. It makes my computer unable to play audio anymore; even though device manager sees my audio hardware, Vista tells me down by the clock that "No Audio Output Device is installed".
And my computer's PC speaker beeps loudly every time a dialog box pops. It's driving me crazy (and, I suspect, those around me).
I found a Web site (http://www.microsoft.com/communities/newsgroups/list/en-us/default.aspx?dg=microsoft.public.windows.64bit.general&tid=acac685a-fd01-4bb1-ac64-da14dbd1c35a&cat=&lang=&cr=&sloc=&p=1) where Microsoft recommended this RealTek driver (http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=23&PFid=23&Level=4&Conn=3&DownTypeID=3&GetDown=false) to fix it. I tried it, but it didn't work.
However, I just got audio working again. Here's how:
1. Go to to "Control Panel > System" (WindowsKey+Pause|Break)
2. Click on "Device Manager"
3. Open the tree "Sound, video and game controllers"
4. Right-click on the audio device and choose "Properties"
5. Select the "Driver" tab
6. Click on the "Update Driver..." button
7. Choose the bottom button: "Browse my computer for driver software"
8. Choose the button _below_ the browse field: "Let me pick from a list of device drivers on my computer"
9. Choose the driver "High Definition Audio Device" (NOT "IDT High Definition Audio Codec")
10. Click "Next"
11. Click "Yes"
12. Wait for the original Vista driver to be reinstalled
13. Click "Close"I hope no one else runs into this, but this fix worked for me. It doesn’t even need a reboot.
can someone please email me back about a solution for windows vista no audio output because i have tried & read all the alerts and no one had a solutionIn Intel site, find this driver:AUD_allOS_5762x_5713.6v_PV_IDTGUI_v68
Save it and run setup program.
Be happy
Thank you! My ex describes me as a total technoklutz..hence the username. I had just had a new windows update installed and the sound was fine before that and then died...I would never have had the nerve to try things like roll back, so thank you!
Have a great weekend
After much online reseach and headache I finally found a solution. I tried everything from uninstalling and reinstalling 4-5 times, updating the driver, and reading through lots of forums. After a break I came back to my computer with a new approach...Was so excited by how easy it was I figured I needed to share..
First; I went to the control panel, then device manager, and opened up the sound tab. Right click on the driver; sigma tel high and uninstall the driver.
Next; I opened up Dell support Center and went to drivers and downloads. This opens up the dell support web site with your systems info. Then I opened up the Audio tab which shows the driver and that it applies to STAC 92XX C-major HD Audio. DOWNLOAD....and follow the easy to install instructions. Within a couple minutes all was back to normal.
Who can live without the sound on their computer...Best of luck

I had the same problem after one of the upgrades. I, too, lost all sound and the speaker icon had a red "x" over it and it also had the same message "No Audio Output Device is installed". At first I kept trying to do the "System Restore" without any success. To resolve my problem, I went to to Control Panel, Hardware & Sound, Sound - Manage Audio Devices. In the "Playback" tab it first stated that "no devices are installed". I right-clicked and found that with the windows vista upgrade my "Speaker/HP" (RealTek High Definition Audio) was somehow disabled. All I did was select the enable option, hit Apply, then Save. Automatically the "Speaker/HP" device was reinstalled! I tested it right away, and have had sound since.Thanks dude i dont know what i would have done if i did not how to fix this problemCOPPERMINE's tip was priceless.... I reccommend it to everyone who experiences the same problem (before going through registry modifications and such). His advice requires you to delete nothing (because VISTA will simply re-install your hi-def audio device as soon as you come out of the sleep mode).

Hey this is one of my posts and it worked for me http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=3520480&SiteID=17Hello Coppermine...I must thank you for your help. It worked like wonders!! My laptop is Toshiba Portege. I think it does not matter what brand of laptop we have. The Vista Update has caused chaos in the sound system. I had the problem following Windows Service Pack 1 update. Thanks again!
I have a Toshiba Satelliate U305 and have the same problem. Sometimes it works, but 5/6 times it says no audio output device exists.I followed the advice from copperminecottage after having this problem on my Sony Vaio running Vista Home Premium and it fixed it straight away. Cheers mate. B
I'm a little behind updating my system to vista, but after my computer needed it's OS reinstalled, I installed Vista (which I wish I wouldn't have done btw). Anyway, I lost my sound. I went to the Gateway website to download the info I needed but it didn't work. After finding your post, I followed your instructions to uninstall the old and the software, etc and it worked! Thank you!!!!
Thanks so much for your advice. I followed your directions and it worked like a charm!!!
I hope others with this problem will try this advice. It was a quick and easy fix!
kdegsOMG! Thank you so much! I have been without sound for about a month now! I have taken my computer to Geek Squad and everything and they had no clue! This totally worked for me!hey guys, i just wanna say ive been reading everyones problems and possible solutions and have been frustrated with the results. I have visited other forums and forms of help...but i used my own brain and solved this stupid frustrating little catastrophe...and im sure you guys will be kicking yourselves!
Im running vista ultimate x86 with 3 gig ram...so i tried go to control panel and go to hardware and sound and then go to device manager...
Assuming vista has the same menus everywhere this will work....inside the device manager right click video,sound and game controllers...
I tried updating this option loads of times but no luck....so i right clicked it again and clicked on the option which says... "scan for hardware changes"...and after about 3 seconds my sound was fully working and the red little cross in the bottom right hand corner was gone....i was so happy and coulnt believe how simple this was....
so there you go i hope this works for you and problems leave a post...Thanks
ACEhow did you fixed it
hi mate go to my link below....there is an easy solution there!
http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=3725971&SiteID=17After downloading and installing the latest batch of Vista updates yesterday, my Sony VAIO went silent and I got the "No Audio Output Device" message. Very scary! Tried restarting a few times without success, then Googled and found this thread. Checked the various options via Control Panel, including checking Realtek drivers up to date. I did not get as far as uninstalling any drivers or software, as the sound started working again after the following actions:
1. Device Manager - Sound Controllers etc - Scan for Hardware Changes (still no audio device)
2. Put computer to sleep and re-awakened (still no audio device recognised)
3. Restarted computer - Realtek High Definition Audio icon reappeared along with the normal start-up chimes.
OK, I had no sound for a few hours yesterday, but I have restarted a few times since and it's working fine. I'm happy again, but I sure would like to know what went wrong and how it fixed itself again. Anyone got any ideas?
I have a Samsung R60 and had the same problem after updating my Vista with a service pack...This solution worked immediately.
Cheers dude, this really helped me out
PeaTHANKS SO MUCH..I TRIED YOUR SOLUTION AND MY SOUND WORKED INSTANTLY.thanks guys...feels good to know i helped and my solution worked for you...clareman...the problem was that sometimes the sound interfers with applications i.e installing updates or applications....you have to scan for hardware changes because the sound has changed although it is still there...you have o restart once or twice and then it will be 100percent a okay!

bjsltd4444@yahoo.comThis happened to me on HP dv9000 series notebook after installing the Service Pack 1. Same "No Audio Output Device is installed" message on red speaker icon in lower right corner. This was corrected by going to Control Panel, Device Manager, Sound,Video and Game Controller and then opening this to see the device. By "right clicking" on the device I was able to choose "update drivers" and selected to check on the Internet. Within minutes, the drivers were found, installed, and sound is working!!!! YEA!!!! Why couldn't these instructions be given automatically after the Service Pack 1 download or a warning given before the download? Good luck!Thank you. Your message was truly helpful and I can now listen to my new Metallica CD. Much appreciated!
