Hi John, 
sorry if I snap at ya. I'm used to the ocassional wipper-snapper who
just asks something with out doing any research. It seems that your
issue is a bit non-standard which caught me off-gard.

Now it makes sense. You have the rear sound as part of the MB. No wires
there. That was the confusion. The rear panel has:

grey  -side speaker lt blue-line in
black -rear speaker green  -front speaker
orange-center bass  pink   -microphone
-----------------------
left         right
rear         rear

left        right
side        side
    front
    speaker
    
    COMPUTER

center
bass
-----------------------
so, regular two channel sound would just require you hooking up to the
'front speaker' aka green plug.

so the board did not come with a wire to connect to your chassis. This
is where the confusion started. So you have a wire but dont know how to
connect it. 

Pins:
|
|
| |6|7|8| |9|  PCI headers
| |1|2|3|4|5|  PCI headers
|              PCI headers
|              PCI headers
|              PCI headers
|              PCI headers
|
|  HDMI    game
|  header  header
+--------------------------
On most boards, pin 1 is maked in some way--maybe a spot of ink or
red color.

From the manual, it says to do the following for basic 2 channel audio:
audio right->pin 3
audio left ->pin 5
ground     ->pin 6
mic        ->pin 1
pin 8 and pin 9 are for HD audio, what ever that means.

hope this help.
