Can't hear anything, not a single thing

[xXLordSlippyXx]

Ok, so I restarted my computer. And when I tried to play counter-strike after I couldent hear a single thing. It's like playing mute, but I can still hear vent and everything else.

Edit: just found it... its happens with every game :frustrate

I thought about this a lot, but I'm not entirely sure what the problem could be. The only thing I could think of is a messed-up audio codec. It happens in every game, not just Steam games, right? But... you can listen to music and whatnot?
