Hello, I am using a Playstation 3 with a computer monitor with computer speakers to play Crysis 3. When I am flipping through the menu or even watching a movie the audio is perfect and outputs what it is supposed to, but when I go ahead and start Crysis 3 the audio all of a sudden starts to just buzz, and when there is supposed to be noises (like the intro to the game) the buzzing just gets louder and goes crazy. Can someone please help me with this issue? I cant play the game without noise its just frustrating. Thank you!

P.S. At the intro of the game it says Digital 5.1 or something, could it be that my computer speakers are not meant for 5.1 audio?
