Everybody is muted (Halo 5)

Hey, can somebody please help me. When I start a game and look at the scoreboard everybody is muted and I cannot un-mute them. I can’t hear any game chat. Also when look at my friends literally everyone is muted and I can’t change it. I checked settings both for my xbox and on halo. I made sure the MP TEAM CHATTER is turned on. My only guess is that I was banned from chat, but I have no clue why. Can anybody help me!?!?!

Have you looked at the privacy settings on your gamertag? Otherwise, my only other guess is you may have been globally muted due to complaints. If you’re in the Preview program, there’s some glitches that surface like this.
