I have a model 1 genesis, one of the later ones with the redesigned board, and I'm getting fuzzy sound out of all of the outputs. I've tried RF, AV and the front headphone jack. The problem is with the system itself, not any of my connections or equipment. It's not a constant buzzing sound. It's most noticeable when there are higher pitched sounds. It sounds like speakers that have gone bad but I know this isn't the case. Is this a problem with the sound chip? Any other ideas?
