So I called Logitech today to RMA my 680's. Extremely helpful, really nice tech support. They asked me what I had done to troubleshoot the problem, and when I told him, he said I pursued all possible avenues (Thanks guys). Gives me a RMA number, tells me they will be sending me a new set of speakers, all I have to send back is the control pod (as proof of purchase). I however get to keep the old speakes. This is awesome, because the speakers work as long as they're not hooked up to a computer. So does anybody know of a way to get them to work without the control pod (the speakers should work with any amp, I'm thinking more of the sub). Thanks again guys. It just seems like such a waste to have perfectly good speakers sitting there...
