High Definition Audio Device Driver Not Working


  • I have no sound at all.  I have a Toshiba Satellite P105-S9312 which, I read, uses the Conexant CX20551-22 audio codec and supports Intel's High Definition Audio specification.  Vista has recognized my "High Definition Audio Device" (as listed in Device Manager) but says, "This device cannot start. (Code 10)."

    I've tried the usual, "Check for Solutions" and "Driver Update" but no success.

    How can I get my sound working?

  • Hi,

    Does your driver support SPDIF digital output but NOT analog?  If so, that sounds like a problem I had with my Soundmax.  I had to stick my old Audigy in the box to get sound in Vista, since it wouldn't work with onboard or my M-audio Delta.

    (Kudo's to Creative for putting out a WORKING Vista driver for an older product.)

    Maybe this is a general problem with HDA drivers.  I've heard that HDA is part of the movement to "patch the analog hole" as a DRM strategy but they seem to be jumping the gun here :)

  • Check the conexant ac-link audio thread, it seems to have a clever hack that might work for you.

  • Hey JC,


    It seems I spoke too soon.  I did in fact get the drivers to install but they are very unstable.

    I had a lot of BSOD's.  So I went to the site and downloaded the XP drivers and installed them in XPSP2 compatibility mode and everything works great now.

    Try finding this file for your OEM version and install it and then install the OEM sound drivers.

  • Richard,

    Did you ever find a resolution.  I have the exact same issue with my P105.  I get the Code 10 error.  I cannot find a solution anywhere.  Toshiba is clueless from what I can get out of them.

    If you have not found a solution let me know and I will update you if I find something.

  • yeah i have the same problem on the same system as the original post but i am still on xpsp2 so i dont think it is a software issue. i am thinking that it is a chonic , and most likely, hardware issue.  ive been trolling forums for a while now looking for a solution and i havnt found anything for sp2 yet.  any tips would be appreciated.

  • Richard,

    I found the solution, at least for my P105-S6014 model.  This solution has proven useful for several driver issues.

    I was able to install the actual drivers provided by Toshiba for XP.  I unpacked the files into a directory and then went into each file and found all application type files.  Right click on the application file and select proprtie.  Go to the compatibility tab and check the box to run for Windows XP SP2.  After doing that to applications within that file I was then able to run the setup and it installed perfectly.

    I have found this technique will work for othr drivers as well.

    Also, since you have a P105 you probably have a mass storage controller device issue.  I was not able to resolve that.  Then, magically after installing Vista RC2 all my remaining device issues went away.  I now have use of my card reader, usb works the way its suppose to, etc.

    Hope this helps everyone or at least someone.

  • Vista RC2 - I got mine running by uninstall device and auto update then reboot then see my last post on SigmaTel High Def Audio thread.  Hope it works for you.

  • SoundMAX Integrated Digital HD Audio – Here is a Vista Upgrade Fix that worked for me !!!


    I too had the NO SOUND issue and it was driving me crazy . I read several post here about the sound problem. I too had a red X by my speaker icon and no sound. I downloaded the driver several times for SoundMAX Integrated Digital HD Audio. It did no good; my system would not recognize the driver. The error message from the red X continued to say I had no Audio device loaded. Rrrrrrrrr!


    I called HP support. After an hour and a half and three Indian foreign specialist, I was told that they knew of the problem and it was a Microsoft support issue, not their HP machine.  They stated that there was not yet a driver out for Vista. Go figure huh? You gotta love those Indian guys.     “tank you vedy much”.


    I went to the driver section so I could look at the list to draw from. I chose the “Browse for driver software on your computer”. When I went to that screen, instead of hitting the browse button I chose the option below called “Let me pick from a list of device drivers”. When I was brought to the next screen there were two drivers to choose from. I saw my driver and tried that one. Rats, it still did not solve the problem. I repeated the steps above and chose the other driver instead, I chose the

    ‘High Definition Audio device”.  I got a warning that it was not a correct copy and it might cause instability I figured this was the driver for the HDTV devise but I chose it anyway. The red x went away from my speaker icon which was progress but still no sound.


    I then repeated the steps aboveproceeded to  RE-LOADED my SoundMAX Integrated Digital HD Audio driver. The system told me to reboot. I did… and gentlemen, I had sound. My music never sounded so good.


    I believe the problem is that if your system thinks you have the correct driver, it does not reload it. But by changing drivers then going back to the original driver, it forced the system to re-load it. Who knows, after all, I am not a certified geek (Just a closet geek).


    Your mileage may vary.

  • I would uninstall any previous driver and go with MS HD Audio, you may have problems with mic though.  Hope it works.

  • Hi I just switched to Vista Business and I got the "mute problem".
    I have downloaded several drivers but no one works, not even the one from microsoft ( All I can see in the Device Manager is that "High Definition Audio Device" is marked with a warning triangle and I cant find any solutions... Can anyone help me maybe?
    If so please mail me;

  • 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!).

    Anyone have any suggestions?

  • Hey guys, I am having an issue with this HD audio also. I have a HP dv6227cl AMD Turion TL-50 x2 with a gig of ram. My system came with Vista Home Premium, but me being me I never use factory defaults I messed around with Vista Home Premium for about 2 weeks then wiped my drive and per-pared it for tri-boot. Now I have sound in Vista Ultimate and in Linux, but not XP. Everytime I goto install that Microsoft UAA Bus Driver it gives me code 39 "Device cannot start".

    As far as microsoft solutions goes none of their remedies for code 39 work? Anybody else had this problem with HD audio in XP? Apparently I have the mcp51 audio chip which is Conexant HD Audio, but even after installing the UAA bus driver (still getting code 39) then when attempting to install the Conexant driver's they never find the hardware. They scan then the little sound and audio devices applet flashes for a sec then I get either a failure or cannot find audio device.

    Also the integrated 56k modem is not detected either. Same issue with that which I know it has something to do with this HD audio problem. Greatly appreciated any help guys.

    Mine is a Presario 3000 laptop, Conexant hd audio works fine with recording from the built-in microphones with the mircrosoft recorder, but it cannot record anything streaming. I have downloaded and tried many recorder but none of them can locate the sound source except the microphone.


    May be Conexant has a huge flaw ?

    Any help appreciated.

    Saturday, May 10, 2008 11:31 PM
  • What worked for me was unistalling my audio device through device manager than reinstalled it using my mobo cd. I went back to device and looked under audio and said my play back (speakers werent plugged in). So out of curiousety i clicked on recording tab and my mic had a green check next to it (working). I just fooled around with the 3 audio pluggins. I unplugged the one i usually would use (on xp, the red audio plugging) and plugged it into another one (the green plugging) and it worked just like that. I tried adding new codecs and what not and wouldn't work until i uninstalled and reinstalled. Thats how i got my high definition audio device to work on my vista pc.

  • Cause

    There are several causes of Code 39 errors:
    A required device driver is missing.
    A required binary file is corrupted.
    There is a problem with the file I/O process.
    A driver that is referencing an entry point in another binary file is unable to load.
    Recommended resolution

    Reinstall the drivers for this device.

    Uninstall and reinstall the driver

    Uninstall the driver from Device Manager, and then scan for new hardware to install the driver again.

    You may be prompted to provide the path of the driver. Windows may have the driver built-in, or may still have the driver files installed from the last time that you set up the device. However, sometimes, it will open the New Hardware Wizard which may ask for the driver. If you are asked for the driver and you do not have it, you can try to download the latest driver from the hardware vendor’s Web site.
    On the device Properties dialog box, click the Driver tab, and then click Uninstall. Follow the instructions.
    Restart your computer.
    Open Device Manager, click Action, and then click Scan for hardware changes. Follow the instructions.

  • The drivers for the device are listed under "sevices", near the end of the listings there..."windows audio service" and "windows audio endpoint service". Check those settings, then try the following links if the driver is configured to start properly and the services are started, but it still won't work. (wrong driver version, etc.etc..) " ".
