This is a problem I've been having since the very first update and it's driving me nuts. I have 2 Xbox One consoles, 4 controllers, and 2 headsets that came with each system. For whatever reason, chat just stops working. And it's random. The mute light works and I get an audio sound when turning the volume all the way up. Sometimes I can hear people through the headset, other times it comes through the TV. Either case, nobody can hear me using the headset. So I have to switch the Kinect on just to chat, which I hate. It affects both consoles at random times. Both headsets at random times. And all 4 controllers at random times. If chat stops working on one console, it doesn't matter which combination of the 4 controllers or 2 headsets I use, it doesn't work on that console. But it will work on the other console. Then, it will randomly start working again and everyone can hear me fine. Until it does it again. Or it stops working on the other console. Yes I've tried doing the hard reset multiple times and all 4 controllers are updated. Not that it should matter because like I said, this problem has been ongoing since before the update for the controllers.
