I have a similar issue with my front panel audio header. the 9 pin audio connector on the motherboard has the following pin connections labled:
However the two leads from the front of the case each have 4 wires with the following lables and colors.
Bundle 1: GND (black), LIN (Red), MIC BIAS (White), L OUT (GREEN)
Bundle 2: MIC IN (White), RIN (Red), R OUT (Green), GND (Black)
Since the lables don't match and the manual is no help, I'm not sure what leads to connect to what pins.
Can anyone help? Someone else mentioned to me the issue was the leads are using the AC '97 variation but my motherboard is using the new coding for Intel. This might be true, but it still didn't tell me what to connect to what.
