Windows 7: Please help: Audio problems

17 Mar 2010   #1

Windows 7 64
Please help: Audio problems

I have a HP Pavillion dv4 laptop with Windows 7 64 bit installed. Lately, I have been having issues with audio on the computer. Sometimes (but no always), when I shut off or restart my computer the audio will not work when i turn it back on. Over the last couple weeks I have been leaving it in sleep mode, and if I had to restart it and the audio stopped working, I would system restore and the problem would be fixed temporarily.

A few hours ago a Windows update was forced onto my computer, and it restarted after the update was applied. As usual, the audio stopped working, so I tried to do a system restore. I tried restoring to 3 different restore points (and I know that the audio was working at each of these three points), however I cannot seem to get audio back on my computer.

More info about the problem:

ATI High Definition Audio Device

When I go into device manager, it says that the device is working properly

When I try to update driver, it says I have the latest version installed

There is no yellow exclamation mark next to the device in device manager

Audio does not work, and interestingly, if I try to play a song in Media Player I get an error
C00D11B1 and it says the file cannot be played

Also, if try to watch a youtube video, I get no sound (obviously), and the video is extremely choppy even if I let it buffer fully

Applications still all run perfectly, there is just no sound

My computer did not have this problem when I first bought it

I would be happy to provide more specific system specs if needed. I really appreciate any help with this issue.
