Antec P183 V3 front panel audio problems

I've just built a system and I can't get the front panel audio connections to work. I'm using a Gigabyte Z68 UD3H motherboard which has the standard 10 pin HD audio connector on the motherboard. However the only sound I get is a buzzing sound (the exact same as if you were to connect the ring on a TRS connection) I've tried both the AC97 and HDA connection with no luck. The grounded sound doesn't not change when the system is powered down so I assume it must be a ground loop or a bad connection in the case wiring?

I have tested the motherboard connector with another case front panel audio connection and it works fine.

Any ideas?

This might be really obvious but have you got a dedicated sound card? I.E Fatal1ty, Xfi or whatever?

No I don't. Like I said it works with another case's front panel. So it's either my case's audio connection that is broken or something to do with grounding between the other front panel connections.

Going by this particular pinout and a multimeter:

There's a connection between 2 and 4 as well as a connection between 6 and 7

And looking at the connections to the front panel:

Headphones (TRS)

T: 9
R: 5
S: 2+4

Microphone (TRS)

T: 1
R: 3
S: 2+4
