Doesn't seem to be an "Audio" forum and I don't think this belongs in Gen Hardware so here goes. Got an Altec 5.1 system that I bought a long time ago, ~ 4 yrs old? Anyway, just about a week ago it started to crackle at completely random times. I'd be listening to mp3s and it'll crackle. Stop listening at it'll still crackle. By crackle I mean imagine if you are plugging in a powered set of speakers into a sound card, you get almost a loud rustling noise. I've checked all of my connections and they seem fine. It's weird because I can go a couple days with it performing fine then have it crackle every other minute. Ideas?
