Yesterday, I played for several hours and during gameplay no matter whether it is multiplayer or zombie mode the sound kept changing to an annoying popping noise that overtakes all sounds. The mic continues to work and you can communicate with players but all ambient sounds from the game are muted and replaced with this popping sound. I thought it might have been my hdmi cable, my ps3 or even my tv but once the game was reset and restarted it was gone. It didn't happen during every game but happened 5 or 6 times to me yesterday. Anyone having the same problems with their console?
