Cannot hear any sound from WMP, youtube, or any other videos RRS feed

  • Question

  • I use a Vista SP2 HP Pavilion dv6 laptop.  Yesterday suddenly, all sound died on me.  The previous day, I had downloaded flash videos from a website called www.auditchannel.tv (this is a website run by the Institute of Internal Auditors, a global organisation), and was able to hear the sound.  I muted the speaker at that time.  Yesterday, I tried to listen to the same flash videos after unmuting the speaker, but could not hear any sound.  Tried playing videos on Youtube, other videos that I had downloaded earlier, but even there no sound was audible.  Then tried playing my mp3 files on windows media player but got the error message saying "Windows Media Player encountered a problem while playing the file. For additional assistance, click Web Help."

    I've tried everything listed on Microsoft Support sites.  This includes:

    i) going to Device manager and ensuring that all the sound devices are showing as working correctly, and all related drivers are uptodate

    ii) downloading Microsoft Fixit exe files for AudioPlayback and WinMediaPlayer, running the exe files, which reinstalled WMP...

    but the problem was not resolved !

    Would appreciate your help to fix this issue.

    One more point - Day before yesterday night, some automatic updates were downloaded by Windows Update overnight, and when I woke up my machine the following morning, I noticed that it had actually shut down and restarted.  But it seemed that the auto update files had not been fully installed.  So, yesterday night, I ran the Windows Update manually, and installed all the pending updates fully.  Not sure if this sound problem could have been caused by this event - ie. partial installation, then running Windows Update again ??  The auto updates were the following: 

    Cumulative Security Update for Internet Explorer 9 for Windows Vista

    Security Updates for Windows Vista...various

    Windows Malicious Software Removal Tool - December 2013

    Microsoft .NET Framework 4.5.1 for Windows Vista

    ZTEMT Corporation - Bus Controllers and Ports - ZTE...various

    Synaptics - Input - Synaptics PS/2 Port TouchPad

    Definition Update for Windows Defender

  • Hi Jarrod80,

    I did that (uninstalling-reinstalling) several times, but still no sound.  When you reinstalled your sound drivers, did you download a latest version of the IDT HD Audio Codec from the internet or was it from the Recovery disk of your machine ?  When I went to the IDT website, it is said that they have stopped supporting HD Audio Codecs, so I could not find any version to install.  Then I picked up what seemed to be a latest version from the Softpedia website, but that turned out to be a 2008 version, whereas the one that was on my machine prior to this problem occurring was a 2009 version.  The reinstall process picks up the 2009 version by default from the Recovery disk, but that too does not help, because the 2009 version is the one that stopped working in the first place.

    If Microsoft updates are causing this problem, the least they should do is issue a fix for that asap, but I don't know if they will do that ?

  • The internal speakers started working after uninstalling the sound drivers and restarted the machine, after which the system reinstalled the High Definition Audio Device driver, which was hitherto being used for the Headset speakers.

    Today, the external speakers (the ones used by the headset) stopped working. Both the internal and external speakers have the same High Definition Audio Device driver. Both are showing "device is working properly", but when the headset is plugged into the two jacks (in and out), the sound does not come from the headset earpiece, but from the internal speakers (ie the loudspeakers). Any solution for this ? 

    My wife's machine has been having a similar, though not identical problem, since the last couple of weeks. In her case, when the headset is plugged in, there is no sound at all, neither from the headset speakers, nor from the internal speakers. 

    Just to eliminate the possibility of the headsets malfunctioning, I tried using another headset, but with the same results as above.

    All these audio problems started a couple of weeks ago, after a Windows overnight update, as detailed in my opening post under this thread.
