Connecting Front Audio

By JohnD5000

  1. I got a new motherboard and case. The case has front microphone and headphone ports and I have been messing around with the plugs to try and get them working but have had no success. There's 7 plugs on the case and 9 pins on the motherboard (There's 10 spaces but only 9 with pis the other is labled NC) and most of the names are different. I was wondering if anybody could help and tell me where they go. The plugs and pins are:


    1. MIC_L
    2. GND
    3. MIC_R
    4. VCC5
    5. Line-out_R
    6. MIC2_JD
    7. Front to Sense
    8. NC
    9. Line-out_L
    10. Line_JD


    MIC IN

    I did a bit of research and found that the solution is probably:

    1. MIC IN
    2. GROUND
    3. MIC-POWER
    5. R-OUT
    6. R-RET
    9. L-OUT
    10. L-RET

    However this still doesn't work. I posted this up onto another couple of forums where people have suggested another couple of possible combinations. Also someone there told me that I should change my audio to analog. I'm yet to try these things but I was just wondering if anyone here had any other suggestions or can back up that changing it audio to analog may work. I'm also not sure about how to go about changing it. Do I do it through hardware or software?

    First off your mobo doesn't support left and right return so they shouldn't be connected at all.

    Your case doesn't support a stereo microphone also.

    So, for headphone socket, 5 to r-out and 9 to l-out.
    Ground to ground obviously.

    For the microphone, 6 probably mic power. Mic in either 2 or 3 or both.

    The reason that the case L and R return aren't used is because your mobo doesn't support a switched socket where the speakers would be cut off when headphones are inserted.

    I'm not %100 sure on the microphone but i am on the headphone side of things.

    Hey, thanks for the help. After a lot of messing around I finaly got it working. The final combinaion that worked was:

    1. MIC IN
    2. GROUND
    4. MIC-POWER
    5. R-OUT
    9. L-OUT

    Although that wasn't the main problem as the microphone socket still didn't work with this before. I had to go into my audio options and check the option "Disable front panel jack detection" so that both the front jack ports work.

    Just thought I'd post here for future reference.
