Since last night I have been unable to speak in party chat or game chat. I am able to hear all of my friends talking, i can send them voice messages so it is not the headset I am using. I do not have a kinect and it is most likely not connection/router problems as this has never happened before. and nothing has changed. I did have a communication ban the day before it happened and when my ban finished it started this problem.
If anyone has any ideas as what the problem is it would be greatly appreciated.
