Terrible supreme fx audio.

So my new board the asus rog rampage 10 comeS with a front slot little audio amp thing that attaches by usb header and is powered by molex I belive, can't remember that one but owell. here is the thing instead of great audio I get this terrible whiney audio with a crazy level of background noise. also when the cpu and gpu get under high load it gets louder to the point of just be noise and audio, stop the sound and it sounds like when a speaker cable is plugged in half way. what the heck is going on here? any ideas?

if its not isolated from the motherboard, then when your system is under load and drawing more wattage, there is going to be interference or "noise"

Well that's a pretty crappy concept then....
