Front Panel Audio connector help needed

So I basically have a very odd front panel audio connector setup, very confusing, I've made over 10 thread on different forums and non were able to help me.

I'm using a Gigabyte G31 motherboard GIGABYTE - Motherboard - Socket 775 - GA-G31M-ES2L (rev. 1.x)

Manual page for the motherboard output can be found below the first image

The front panel audio connectors consists of:
Yellow- MIC BIAS
Green - SPKOUT R
Peach - MIC In
Blue - Return L
Black - Ground
White - SPKOUT L
Grey - SPKOUT L





Much Thanks and appreciation to those who read this read

Your front panel connections aren't odd, but they are old. They are for the AC97 standard.

Set your onbaord audio to AC97 in the BIOS set-up.

The AC97 pinouts are here:

Desktop Boards — Front panel audio header pinouts

1 Mic In
2 Ground
3 Mic Bias
5 Spkout R
9 Spkout L

It looks like the onboard audio doesn't support the Return lines.

There should only be one Spkout L connector. It's the white (not gray) one.

Have you really been trying to figure this out for 5 months? Yikes.

If these connections cause your PC to go up in a fireball, don't blame me.
