How to set AAFP connectors if i have and old chasis

[Paul_270]

So I have an old chasis with a front panel audio that suports microphone and headsets.

The cables from my chasis are this: G G R MIC and my AAFP connectors look like all the others. The motherboard name is ASUS 7Z170-K

The front panel audio can be configured to AC'97 or HD audio. Default BIOS setting is HD audio.

Pin outs for wiring, location of headers, and BIOS setting are found in the downloadable motherboard manual.

I've set to AC97 but I don't know how to connect the pins. AS I said I have only 4 pins: G G R MIC but the AAFP has some diferent pins like mic2, micpwr, agnd, line our R, line out L, NC ...

Can you point how should I connect them ? Thanks
