I just picked up a 7.1 system, Panasonic SC-HT200 and hooked it up to my computer via RCA audio cables.

There's a constant buzzing coming from the subwoofer, doesn't matter if I mute all sounds from the computer, the buzzing doesn't go away. Checked that the plug is fully inserted. Tested the same RCA cable by hooking up the Xbox 360 to the sound system, and there's no buzzing. Checked other audio sources and the speakers and sub work fine when playing a DVD or using hte ipod dock.

What the heck is the signal coming from the computer that's causing the subwoofer to buzz, even when nothing is playing? I have an Auzentech X-Plosion soundcard, my old speakers work just fine using the same connection (no buzzing). I'm really really stumped.
