I have a Klipsch SWS add-on subwoofer hooked up to my 5.1 ultra system and when the SWS is hooked up I get a buzzing noise through the speakers. When I start a pc game it gets worse. Even moving my mouse or scrolling down on a website changes the buzzing sound. I have tried all new power cords and 3.5mm stereo wires to and from the ultra sub and sound card. I even plugged the two subs into their own separate outlets....If I disconnect the SWS from the system and just use my 5.1 ultra everything is good. I'm guessing something is fried on the SWS panel?
On a side note, even if I turn the volume to 0 on the volume control pod of the 5.1 the buzzing is not affected. It's still there. Even if I turn off the power switch on the SWS sub the problem persists. I've jiggled cables, replaced cables etc... It just seems weird that the buzzing and sometimes a slight screeching sound will go up and down with anything related to video movement on screen. When playing a game the faster the video frame rates the faster and louder the buzz. Slower frame rate is slower and lower buzzing noise.
Like I say once the SWS is eliminated from the mix all issues go away. My 5.1 works awesome by itself.
Any help or trouble shooting tips would be appreciated.
Thanks,
Damon
