Broken audio on PS3

I just bought Skate 3 second hand for Playstation 3 and I got some kind of audio glitch.

There is a constant annoying sound, as if one sound repeats itself over and over again. No other sounds can come through, so no music or skate-sounds in-game.

I tried deleting and re-installing the game files, but that didn't help.

Is this a known bug and can I do something about this?

Please help!
