Audio connection

I have the following:

Audio header:

AGND | +5VA | BLINE_OUT_R | nc | BLINE_OUT_L
—–|——–|————-|—-|————
MIC2 | MICPWR | Line out_R | nc | Line out_L

Audio cable 1 Audio cable 2

GND (black) GND (black)
L-IN (white) R-IN (white
L-OUT (red) R-OUT (red)
MIC-IN (green) MIC-IN (orange)

I was told this’s a special situation that requires a special cable. It’s an AXIO 732SL case with a ASUS A7V8X-X motherboard. I contacted ASUS regarding this. They responded by telling me to contact AXIO. Thet have no way of being contacted – that I can see.
