I hope this finds you well. For the past week myself under my gamertag and my roommate under his gamertag haven't been able to participate in chat. I already checked to see if I was under a communication suspension without any notification...and according to your site I wasn't under one. Now, that being said we bought another headset in case the headset was malfunctioning. That is not the case out of 3 xbox headsets and 3 controllers - logged in under either gamer tag we can hear communication from other players, we can participate and all three controllers work perfectly fine. All three microphone/headsets are registering when connected to any of the three controllers as it being connected, all three led lights light up when the mute button on the left side is pressed, all three headsets register the volume up or down notification sound on any of the 3 controllers when connected. Both gamertags can receive and send game/party invites. The game invites - no problem - the party invites are fine, except for the fact our microphones will not send the audio. In a party with each other on our separate consoles - we can log in but neither of us can hear each other through our headsets. Could someone please assist. I have already tweeted multiple times for help.
