I'm a little confused. I haven't played in a couple weeks, but last time I played I didn't have this problem.
Every lobby I got into tonight no one was muted in the lobby, but once the game started if I bring up the scoreboard everyone has a red X over the speaker icon indicating that everyone is muted. I tried to unmute them and I couldn't. If I started a party and invited people to my party I can hear them just fine, but again everyone else is muted even if I set my party preferences to game chat. so I'm just wondering if this was something that was added during the last patch even though it wasn't in the notes, or if it's just me having this problem.
Thanks, I am apparently an idiot. I forgot that I got tired of little kids sending the all recent players messages, so I changed my contact preferences to friends only.I guess I just didn't realize that included in game voice audio.
Oh well the trade off is totally worth it to not have those annoying messages every time I play.
