I have a 7.1 sound setup on my pc. I have had no trouble with any game, but for some reason i can only get 2.1 sound or 5.1 sound with this game. 7.1 dosent work, I set it to 5.1 and that works but when i set it to windows default in the sound options... it goes to 2.1 which doesnt make sense considering my default in windows is 7.1. anyone else have this problem?
