I need to connect my front audio wires to my motherboard. However, the cabinet is pretty old, from 2007. But my motherboard is a gigabyte mb bought in 2013. I think that my cabinet has AC 97 system of wires. I went through the motherboard guide but can't seem to understand how to connect the wires to the motherboard pins. The names given on the guide do not match the names printed on my cabinet wires. Please help me connect them. Here are what's written on the cabinet wires - Mic 2, Gnd, Mic 2 , SPK - R, SPK - L.
