Annoying noise when front pannel usb and audio plugged in

Just wondering if someone will give me a hand with this as its really annoying me.

I get a really annoying buzzing noise in my headphones if I've got the front pannel usb plugged into my motherboard.

I think the frontpannel shares the same ground or something since I only get it with the USB plugged in

.

I've got a gigabyte ga-x58-usb3 motherboad and using its onboard sound and usb.

I've got a Xigmatek midgard Case.

Is there anyway of fixing this without having to buy a whole new case or motherboard?

Try isolating the front panel audio from the rest of the case as it does sound like a ground loop, not sure how easy that will be though in that case.

Just took some photos of the front pannel internals,

Any idea how i'd issolate these?

Have you tried connecting your headphones with both things removed from the case? It could be a simple case of one of the screws causing the Earth. I have to say though, being both USB and front audio together might make it more difficult; I assume one of those 2 connections is some propriety USB header connection? Remove that and it might work and if that's the case we can work forward from there.

Removed the USB header and theres no noise at all anymore.

Plugged it back in and the noise comes back.

The USB header is the one on the left side of the circuit board with two wires coming out of it.
