How to map case audio to MB???

[Mawashi]

My MB has the following diagram:

Audio Header
1 Aud_Mic
2 Aud_Gnd
3 Aud_Mic_Bias
4 Aud_Vcc
5 Aud_Fpout_R
6 Aud_Ret_R
7 HP_On
8 Key (no pin)
9 Aud_Fpout_L
10 Aud_Ret_L

My Case has:
R_ret
R_out
Ground
Mic_in
Mic_Power
L_out
L_ret

Does anyone knows what goes with Aud_Mic, Aud_Mic_Bias and Aud_Vcc? So far this is what i came up with:

1 Aud_Mic With ???
2 Aud_Gnd With Ground
3 Aud_Mic_Bias With ???
4 Aud_Vcc With ???
5 Aud_Fpout_R With R_out
6 Aud_Ret_R With R_ret
7 HP_On With Nothing
8 Key (no pin) With Nothing
9 Aud_Fpout_L with L_out
10 Aud_Ret_L with L_ret

Thanks!

AudMic - MicPower
AudMicBias - MicIn

Not sure about the last though. But this should be in manual for either case or motherboard. You can probably find those manuals, at the manufacturers website.

Thanks JZilla! Don't know what the last one is for neither but everything works anyway!
