Hi all, I have recently noticed I am getting some kind of interference affecting my audigy 2zs sound card. I think it's interference, it sort of buzzes (through the speakers, not the actual card) when you move the mouse, like when you're using crappy onboard sound. It still does it when the volume is turned down all the way to 0 in windows. It can be reduced a bit by turning the volume up in windows and down on the speakers, as the volume of the buzzing remains constant regardless of windows volume level, but obviously is amplified when the speaker volume is turned up. Is this EMI? And why has it only started doing it now?
