I was playing the final mission when all of a sudden the sound when out on the mission. The sound was working fine through the escape part of Captured, the sound disappeared when the underwater section of the level began. The game sound is still there as I backed out to the main menu and could hear sounds as I would scroll the menu. I have saved the game, exited, cleared cache and restarted andI still there is no sound present. Not sure what to do next. I tried just to finish the level but when I get to the part where my partner AST needs to bust through the door to disarm the missile, he just stands there. Anyone have any advice? Thank you.
