My "no audio" problem started after installing WMP11 and numerous Msft updates. Not using any audio apps lately, I didn't discover the problem till just recently. I don't know if these files were deleted as part of one of the updates, adding the newer Player, or because I deleted Jukebox and MUSICMATCH, Sony Media, which plays CDs and DVDs.Just ran "Autoruns" and found these files missing from the Drivers folder. Are these even relevant?

HKLM\System\CurrentControlSet\Services

Changer File not found: C:\WINDOWS\System32\Drivers\Changer.sys
CO_Mon File not found: C:\WINDOWS\system32\Drivers\CO_Mon.sys
i2omgmt File not found: C:\WINDOWS\System32\Drivers\i2omgmt.sys
lbrtfdc File not found: C:\WINDOWS\System32\Drivers\lbrtfdc.sys
PCIDump File not found: C:\WINDOWS\System32\Drivers\PCIDump.sys
PDCOMP File not found: C:\WINDOWS\System32\Drivers\PDCOMP.sys
PDFRAME File not found: C:\WINDOWS\System32\Drivers\PDFRAME.sys
PDRELI File not found: C:\WINDOWS\System32\Drivers\PDRELI.sys
PDRFRAME File not found: C:\WINDOWS\System32\Drivers\PDRFRAME.sys
WDICA File not found: C:\WINDOWS\System32\Drivers\WDICA.sys

If these are needed, is there a way to obtain those files and put them back in the Drivers folder, or are they even part of the problem? I bought DriverDetective the other day and updated 14 drivers, all successfully. Everything in device manager says the drivers are fine, & device(s) working properly. That's odd because the Drive won't play a CD, there's no audio with a DVD, & no audio from other file types on my laptop. Sonic Stage will play a CD just fine, while WMP gives this error:

"Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly."

If there's any other information I can provide that would help someone more experienced than me to figure this out, I'd be glad to do so. Was just searching online for anything else relevant and found someone posting about these drivers too, but don't believe he was having an audio problem. Apparently, he just found this out while using Autoruns. http://forum.sysinternals.com/forum_posts.asp?TID=11781

Last of all, would posting a HiJackThis log be of any value?

Many thanks,
Mike

Looking at some of the errors, I would suggest you run system file checker.
