Same thing happened to me (on xbox one), the game was working just fine for a while, then suddenly the sound stopped in the middle of a game. I restarted the game, now the sound only plays in the AB intro, but I get no other sound. Further, when I'm in a game, aside from having no sound, I'm seeing various glitches where the replays have players disappearing, and the game stopping altogether in transitions such as kickoffs or end of quarters. This is completely unplayable and unacceptable as it is, I've never experienced so many bugs before in a game. Either this needs to be addressed asap, or we should get refunds!
