I've had a Paradigm system for about 2 months and have not had any issues at all, however, when I came home from work today there was a horrible sounding buzz from the subwoofer. When it was powered up the noise disappeared and when it was unplugged there was no sound. There was a horrible noise while it was plugged-in, both when the subwoofer audio cable was connected or not.
Suggestions on how to fix this? I had a custom install, with cables buried in the wall and the installer put in a ground loop.
Thanks,
