My in game voice chat has not been working for the last few months. It was working fine until one day it just stopped. I cannot hear anyone, and no one can hear me. I can hear all other in game sounds, so I know that the game's audio is working. When I press my push to talk key, I see the indicator for talking, so I know that my microphone is working fine. I have already tried changing (as well as resetting to default) all of the settings in the game. I have also tried using a different headset.
