So this morning i was watching TV (hdtv cable box hooked up to my pioneer reciever) and everything is just gravy. I take a shower, come back, and my roommate is watching TV but there is this hideous crackling/popping sound coming out of EVERY speaker, even the factory TV speakers. Ive changed cables, swapped speaker sides from left to right, etc.. What is the deal? Is it static electricity? Can it be fixed easily? Any help is appreciated.
