So I was playing Black Ops 2 just now and whenever I'm in the game neither Teamspeak nor Mumble will pick up what I'm saying. I can still hear other people talking, but nobody can hear me. Once I exit the game everybody can hear me again. Anyone know a fix to this?
is there in-game communication? Maybe it's holding the audio device (your mic) hostage from other applications. Try disabling it or changing the input to something else that you're not using (like Line In)
