Do you hear the hum when you use a pair of headphones ?
I use only headphones and they're pretty decent,(Seinheiser 515.) It becomes very noticeable when I turn the volume up more than half way in alsa. Even when it's half way I can hear it when there's no sound coming through. And I don't have this issue when I'm using them for my 360 so I don't think it's a hardware problem.
