This problem has been happening since the beginning. Chat sometimes works through my headset, then sometimes it doesn't. It will stop working at different times doing different things. Just now I was playing Titanfall and my chat was working, then after the round my chat stopped working. The headset is not the issue as I have two headsets and they both do the same thing. The headset powers on, just doesn't register my voice or allow other players to come through either. The amount of glitches with this system is amazing lol.
