    hello..

    i have an elitegroup 848P-A mobo
    and im trying to connect a stereo jack and mic jack that are on the front of my case..
    i have the stereo jack working fine, but i cant get my head around the mic...

    there is 3 wires for the mic jack on the case, these are:
    • MIC VDD
    • MIC GND
    • MIC DATA

    and the 3 remaining pins on the motherboard are:
    • AUD_MIC
    • AUD_MIC_BIAS
    • AUD_VCC

    im trying to match them up with little success... any ideas what needs to go where?

    cheers

    Im gonna take an educated guess here :)

    AUD mic - MIC data
    AUD mic bias - MIC gnd
    AUD vcc - vdd

    If that doesnt work just try different combos :), its wont break anything if they are wrong.
