Microphone In Use By Game

Just a small little bit of a bug. I was playing ball race and talking to a friend and without pushing my push-to-talk key, my microphone wasn’t transmitting over the call in steam voice chat.

Not a bug. A lot of Steam games do this. If the game has in-game chat, then it will override the Steam voice chat, which is why it says that the microphone is in use by the game.
