No Audio Output- How do I fix this?

  1. I have an Asus p5n-d mobo and have assembled it into my computer, and everything works, except for my speakers. I have tried them on my laptop and they are fully functional, but none of the audio... speaker holes work.

    I am fairly sure where the front panel plugs should be connected to the motherboard (in the southwest corner, cpu being center north), and there is a set of 9 pins, like this
    [:::.:]
    or
    a b c -- e
    a b c d e (for reference)

    I have two setups for the pins in my booklet that came with my mobo
    there is an Azalia-compliant pin definition, and a Legacy AC 97-con pin definition. I don't know what this means.
    There are charts for the pin definitions, however they do not match the front panel cord sections.

    Azalia..........a.................b......................c...................d.....................e
    ...........[....(gnd) ...(presence#)...(sense1_retur).......(---) .......(sense2_retur).]
    ...........[.(port1L)........(port1R)..........(port2R)....(sense_send).....(port2L)......]

    Legacy........a..................b...................c...............d...............e
    ...............[(AGND)........(N/C) ............(N/C)......... (---).........(N/C).......]
    ...............[.(MIC2).....(MICPWR)....(line out R).....(N/C)....(line out L).]

    The front panel audio connection cord has
    some mic sections ...(power, bias)
    some speaker left ....(return, (some other thing))
    Some speaker Right (Return, other)
    And a ground ...........(Ground)

    So i have only 7 acceptors for 9 pins
    I tried connecting them in reasonable configuration, with Legacy, because it seemed to fit better with my acceptors, so i tried with the ground in AGND, and Mic Bias and power in Mic 2 and pwr respectively. Line out R and the one above it have the speaker Right acc, the same with line out L and the one above it. I tried without putting acc's on the pins above line out L and R, but it didnt work that way either.

    In any case, the speakers wont work, and i really would appreciate help in the matter.
    Thank you!

    Your first example is AC97 audio... HD Audio uses more pins but I don't have a reference in front of me at the moment
