So I was on matchmaking on Halo 3 and these guys we’re being really annoying so I went to game setting and put “Mute” and then I played and turned my console off. The next time I went on I put it to “Not Mute” and then played but when I was playing I couldn’t talk or hear people. At the bottom – right corner there was a circle with a diagonal line through it. I have 2 headsets and it won’t work for both. can anyone help?
