is anyone else expiring sound problems on FC4. after i tried co op when i returned to my game a bunch of the sounds did not work. i cannot hear people talking doors opening, guns being fired, or my person jumping. however i can still hear the wind/ background noise and the music. theres barley any sound options, and you cannot go back to a previous save. it seems as if my game saved with the sound off so now no matter war mode I'm in i have none of the sounds that are important. i tried re installing the game and a few other things nothing worked.
