I recently purchased a reconditioned PS3 - one of the early models that is backward compatible. Problem is that when I try to play a PS3 game the audio dies. I get full audio in other modes (DVD, PS and PS2), even for the game's main screen, but the audio is dead when I enter the game itself. I've tried everything I can, including some of the suggestions on Playstation's help site, but still can't get it to work. Any suggestions would be appreciated.
