My buddy who lives in the Philippines has been unable to talk to us via his headset in an Xbox One Party since Destiny was released. He had no problems when we used to play Titanfall but it hasn't worked since (with Destiny, Halo-Master Chief Collection, and now HALO 5). He can join the party and he can sometimes hear us but we can never hear him. As you would imagine it makes it difficult to play.
Does anyone have any suggestions? Thanks!
