I'm running Windows XP, and last night my PC was infected by a frustrating virus (one of those viruses that won't let you open virus checkers, etc). I finally killed it 2 hours later, but it involved some heavy duty anti-dote. One side effect is my audio is now gone.
Except it's not entirely gone, because when I open the Realtek HD Audio Manager in the task bar, I can play all the "test" sounds. The speakers, the sound card, etc, are therefore working fine.
But things like YouTube or Windows Media Player, there's no sound.
I'm guessing there's a setting that needs to be reconfigured somewhere.. but where?
Maybe relevant: One thing I did do last night was "play" with the system registry.
Any help would be greatly appreciated.
Thanks.
SOLVED!
The two hour battle with my computer virus resulted in my computer permanently thinking it was in Safe Mode, regardless of how it booted up.
I was able to "fix" this by following the post by hsandler in this thread: http://www.petri.co.il/forums/showthread.php?t=23032&page=2
I then rebooted.. and let me tell you, the Windows Startup music has never sounded so sweet.
Thanks to all, especially James, whose advice gave me a major clue as to what the problem was.
