I think your connectors are following the AC 97 format.
If you imagine the connector like this....
Pin 10 [
XX] 9
_Pin 8 [
OX] 7
_Pin 6 [
XX] 5
_Pin 4 [
XX] 3
_Pin 2 [
XX] 1
The the following pins correspond to your headers:
1 MIC = MIC IN(R) | Green
2 AUD_GND = GND | Black
3 MIC_BIAS = MIC POWER (L) | Orange
4 AUD_GND = N/a
5 FP_OUT_R = LINE OUT FR | Red
6 FP_RETURN_R = LINE OUT RR | Blue
7 AUD_5V = N/a
8 KEY No pin = N/a (this is the one without the pin)
9 FP_OUT_L = LINE OUT FL | White
10 FP_RETURN_L = LINE OUT RL | Yellow
