This might sound stupid, but are you sure the noise you're hearing is actually digital distortion? USB soundcard vendors tend to be disregardful with regard to power supply, and that would mostly be auditable when there is other traffic on the bus. Does this also happen with other operating systems? Any chance you can record the noise you hear?
