    Front panel audio header (9-pin HD_Audio) / REALTEK HD

    I have got an Asrock 4COREDUAL-SATA2R2.0 and when I check its manual then it shows the setting for the 9 pins like the following:
    1. MIC2_L
    2. GND
    3. MIC_R
    4. PRESENCE#
    5. OUT2_R
    6. MIC_RET
    7. J_SENSE
    8. NO PIN
    9. OUT2_L
    10. OUT_RET

    But the pc case that I have, it has the wires named as the following:
    1. GND ( BLACK COLOUR)
    2. GND ( BLACK COLOUR)
    3. MIC_IN ( RED COLOUR)
    4. MIC_BIAS ( WHITE COLOUR)
    5. SPKOUT_L (WHITE COLOUR)
    6. SPKOUT_R (GREEN COLOUR)
    7. RETURN_R ( GRAY COLOUR)
    8. NO PIN
    9. RETURN_L ( WHITE COLOUR)
    10. NIL

    So, can anyone tell me how to match those named wires with the above setting of my new panel?

    I found out the below things in the Asrock manual:

    MIC2_L X X GND
    MIC2_R X X PRESENCE#
    OUT2_R X X MIC_RET
    J_Sense X <--- no pin
    OUT2_L X X OUT_RET

    The J_Sense, MIC_RET, and OUT_RET are part of plug sensing, and are not required or supported on the majority of computer cases. The PRESENCE# pin, when a wire is connected to it, can be used to indicate that the other three wires are valid. You do not need to make a connection to any of them. Thus, this is what the Asrock header really looks like. These are the pins that make the audio.

    MIC2_L X X GND
    MIC2_R X X
    OUT2_R X X
    X <--- no pin
    OUT2_L X X

    The wires would connect to the pins, like this.

    MIC_IN ----- MIC2_L X X GND ----- GND wire
    MIC_BIAS --- MIC2_R X X
    SPKOUT_R --- OUT2_R X X
    X <--- no pin
    SPKOUT_L --- OUT2_L X X

    It seems to me that the motherboard that you have and the panel are not designed to be connected. You will need to contact the case manufacturer for this kind of problem that you are facing. I dont think that Windows XP can be configured to solve the issue.
