What I assume you are trying to do is hook up the motherboard nine audio pins to a computer case wire harness is this correct?
If I am correct, what labeling do you see on each of the case wire plugs?
They would have labeling such as HDD, Speaker ect.
Now perhaps your case may have some labeling such as micr+ and micl+ and so on.
When reference is given to power and audio, this is often used when special external audio related devices are attached to the motherboard.
It depends on the type of device.
Such devices can be a synthesizer keyboard which simulates an electronic organ/piano and those devices depend solely on power coming from the motherboard, such as how USB devices are powered.
If you can supply me with the model of the motherboard, I can obtain a copy of the motherboard manual and determine exactly what those 9 pins are intended for, besides my assuming what they are for.
If your motherboard has AC'97 Front Panel Audio, it is likely you have a RealTek audio chip built into your motherboard.
Once I know your exact motherboard make and model number, I will have a better idea what we are working with here.
