I seem to have an issue with the chat feature in this game that continues to get extremely frustrating. When in a public game with a specific friend, I cannot hear him and he cannot here me, regardless of game settings, fireteam, no fireteam, etc. Nothing works. I can hear everyone else in-game without any issues. He can hear everyone else in-game without any issue. His mic never shows active on my scoreboard. Mine never shows active on his scoreboard. What further confuses the hell out of us is we can play co-op campaign or challanges and have no problems with communication what so ever. This is only happening with one specific person and only during public games regardless of settings. This has gone on since day one and we have exhausted all options we can think of. What could possibly be causing this to happen? Any input at all or anyone else having similar problems with VoIP in this game? Thanks in advance for any input.
