My sounds been fuxxored, help please

So I was in gikobar, broadcasting on the microphones, right?  Had everythin working normal.  Then I got on AIM and tried to turn on the talk function to play the same music to somebody not on gikobar.  And then after a few seconds of working, I heard this "BLIP" and it suddenly stopped.  I couldn't get the music to start again, even after restarting my computer.

Please help me.  I'll be watching this thread closely so I can provide any details you need to help me.  Thanks much.

Anybody help me?  I'm gonna ask /g/ then...they say to ask questions here...but nobody is answering.
