Unable to unmute mic- xbox one

Hello everyone.
I currently use xbox one to play OW2 and even since OW1 I am having issues with my mic in the middle of the game just muting on its own and I’m unable to unmute myself. I can’t hear my group/teammates. Sometimes in the beginning of the match I’m automatically muted and I believe I’m not banned as I don’t personally recall doing anything to deserve a ban. I even bought a new headset and controller so I’m wasting money at this point and I hopefully want this fixed as I am super frustrated.

Also if I am in an xbox party, it works. Only OW2 is the trouble I have.
