I can't help you much with this, except that a few years ago I had a very similar problem but using the built-in sound on a Asus motherboard - intermittent and unpredictable faint buzz.  But then I found some sort of kernel setting/boot parameter which switched off (or possibly on) something and the problem was cured.  The trouble is, I can't remember what it was!  But at least in my case what sounded like electrical interference was actually software "interference", so it might be worth your while searching a bit further.
