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 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.
Day before yesterday night, some automatic updates were downloaded by Windows Update overnight, and when I woke up my machine the following morning, 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 - 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
