Topic: Bioshock Audio Weirdness

From what I gather, I'm not alone in experiencing audio issues in the game. I'm still playing the first game, and in the part where you're in the fishery, and get the camera to take pictures, for most of the level after that, I kept hearing a sound like one of the turrets was shooting and hitting something metal. Even when I was in a room with no turrets. At the part where you have to burn off the ice from the doors, I could faintly hear the sound. It went away, I think, during the last bit of the level where you have to get to the transport pod for Atlas's family.
