Need front panel audio connector help

[*SlyVenom*]

I can't figure out how to connect the old
front panel audio connections to a new motherboard.

The front panel has a mic and headphone jack.
The old mobo was an Imperial GL VE
The new Mobo is an Asus P4V8X-MX

The new mobo uses a standard intel 10-1 pin audio

(1)Mic 2...............(2)Agnd
(3)Micpwr............(4)+5VA
(5)Line_out_R......(6)BLine_out_R
(7)NC.................(8)No pin
(9)Line_out_L.......(10)BLine_out_L

Case = eMachines T1742 two sets 3(4)-wire connectors unmarked

(set1) headphones(3) = red, thick black, yellowish orange
(set2) Mic(4) =red, Thick Black, no connector, yellow

The mobo came with jumpers at positions 5:6 and 9:10,
to route the audio to the back port for speakers.
If I remove these, I won't get speaker sound.

Can someone help me determine which wire goes where?
I have tried to do enough research to determine the configuration,
I am thinking the fat black wires are ground, but I'm not 100% certain,
also I'm thinking I should be able to attach the left and right to pins 5&6 and 9&10 to maintain front and rear headphone&speaker usage.

I defiantly would like some reassurance a second opinion before I try it and short something.

Thanks in advance,
Mike

I found this thread that does discuss this issue and has someone's 7 pin wiring code with colours - if you have a decent voltmeter you might be able to cross check stuff:

Thank you,
although it wasn't exactly the same connection,
it gave me some good insight to back up my educated guess.

Well, I found a 10-pin connector in my drawer at work,
so I got out the soldering iron and the multi-meter
and gave my idea a try,

I split the red speaker wire to pins 5 & 6
and the yellow speaker wire to pins 9 & 10
I had to attach them to both for the rear audio to work.

And I put both grounds into pin 2

The sound works perfectly,
unfortuantley you need powered speaker in the rear
as they won't disable if you plug headphones in the front.

I attached the red mic wire to pin 1
and the yellow to pin 3

I haven't tested the mic yet,
as I'm a little leary of cooking it.

Will it wreck the mic if I got the mic and micpower reversed?
