I have this problem and it just won't work, works in every other game, when you check who is online every other player has the mic logo next to their name but none for me, this means I can not communicate with anyone in game and also means I get shot on sight, I have tried to work with it but this just makes this already difficult and tedious game not worth the time and effort which is a real shame because it is most likely the only real game left that offers any kind of meaningful challenge.
I also went as far as getting the new wireless Xbox headset, this should be an indication of how much i want to play this game but even that still won't work, uninstall, alternate mac address, when the mic is set to voice activation the mic icon is always on if the mic is plugged in and always on with the wireless headset.
