I get a strange interference when using the front panel audio jacks of my PC. There is a faint static when the PC is idle and its like a high pitched noise when ever I use something connected to usb (Mouse keyboard, etc) Its extremely annoying. Its only on the front panel. Everything is clear as a bell if I plug into the back. I just have a stock soundcard that came with my motherboard. Nothing fancy (Click for newegg page of motherboard) I guess its a "SupremeFX II". Anyone have idea on what it is and how to fix it?
