How to connect fp mic on msi G31M3-L V2 ?

Question

Hi ,Does anybody knows how to connect front panel mic jack or audio jack, the manual for MSI G31M3-L V2 doesnt says anything about JFP2.  I have already connected the three jacks with 5.1 home theater speaker system, and so i do not have free mic jack for my web cam, or one channel for 5.1 speaker system
Free wires are mic_bias, mic_in, Gnd, Spk .. return L, return R, Thanks!

Hi,
the JFP1 and JFP2 connectors cannot be used for connecting the case's front panel audio ports.  You have to use the JAUD1 Connector.
The Pinouts of the JAUD1 Connector are described in the user manual.  If you want a more detailed pin definition, check the Intel Front Panel I/O Connectivity Design Guide, page 22 (Intel® High Definition Audio):

Looks like your case's wiring is not fully compatible with the Intel HD Audio/Azalia Connectivity Standard, so don't be surprised that the JAUD1 Connector has more pins than you have wires. Connecting the microphone should be pretty easy anyway.  There are basically just two possible positions. The GND-Wire goes to the GND-Pin (2).  The two MIC-Wires go to the two MIC-Pins (1 and 3).  Try both positions, one of them should work.  When you test the microphone and it does not work, make sure you try the following things:
1) Disable the Front Panel Audio Jack Detection in the Realtek HD Audio Manager
2) Run the microphone calibration utility (called miccal.exe (it is in the Realtek Installation folder))
3) Enable Microphone Boost
