Connecting Front Audio to Mobo

[The Hobo]

I recently put together a computer for my girlfriends mom, and I can't figure out how to connect the Front-side Audio connectors to the motherboard.

In the motherboard manual, it has this for pin assignment:

1: MIC
2: GND
3: REF
4: Power
5: Front Audio (R)
6: Rear Audio (R)
7: Reserved
8: No Pin
9: Front Audio (L)
10: Rear Audio (L)

But the connectors on the case are:

MIC IN
MIC BIAS
GROUND
SPKOUT L
SPKOUT R
RETURN L
RETURN R

I'm not sure what is what. Any ideas on how to connect these?

if you have a digital camera, can you take a picture of the connectors from the case and a picture of the motherboard? I MIGHT can help cause I've hooked up front end audio before. Not saying I can work miracles for ya though but i'd like to try

be very careful when attempting this!!!! even if u connect them all up(wrong) and the sound still works but the sound is slighly muffeled and get worse after 30 mins /hour then this is what we call static build up lol, which will screw ur full mobo if left long enough! so only do it if ur 110% positive about where they go...check the manufactures website or manual about it?
