I just recently built my new PC, and when I plugged in my USB headset, the constant static/crackling noise began. I've tried all the USB ports and audio jacks, and I've determined that it's when the USB is plugged in that the sound begins. I've downloaded all the latest audio drivers for my motherboard and that didn't change it a bit, On my older computer it made a slight static noise but nowhere near as bad, any help would be appreciated, thanks.
