There is also a problem when you join a match thats already in session. Every sound in the game will be muted except for your footsteps and one other thing its hard to pinpoint but this happens every time I join a match in session. After we return to the lobby and the next match loads the sound is fixed.
One more problem is the fact of lag. I don't see the lag but when you check the connection status in a multiplayer match you see every player except for the host with three to one bar of connectivity. The host obvisouly has a full connection.
A patch could fix these issues plz EA respond with some feedback because I really like the multiplayer but these things are holding it back.
