I have the same issue with audio. My headset will randomly disconnect then reconnect and when that happens I need to quit to desktop then log back in. Super annoying to have to go through the authentication, log in, load server, wait in queue, and get back into the game only to have it happen again in another hour or so... It's to the point I dont bother anymore and I have no idea how many scenes are voiced in 3.0 because of this...

I have no issues with any other game and the disconnect thing, It blips, i hear the "beedoo... boodee", then shit just works. I have since solved the issue on my end of the disconnecting but from time to time one of the kids or dog will knock the cord out from its new socket and then I'm back to square one.
