Ok... well I got Klipsch Promedia 4.1's for X-Mas and they worked fine for awhile but now they make wierd scractch type noises. Recently, I have tried a few things to try to fix it but nothing has been sucessful. I have found out that the sound is really noticable when the surround sound knob on the control pod thingy is turned up. Right now it is all the way off but the sound is still apparent in most of the songs I listen to. I know I prolly sound like an *** or something cause I'm complaining but when you pay this kind of money for something u expect it to work flawlessly. So, does anyone know of a possible solution or do you think I should return them to Best Buy and see if I can get a new set? Thanks in advanced for any help.
