GA-M55S-S3 F_Audio connections

[Thexter711]

I'm building myself a computer and have a quick question about the front audio connectors. My problem is that the mobo manual has connectors listed under a different name from the actual connectors my tower has. The picture below shows my mobo F_Aduio pins, the mobo manual about the F_Audio pins, and the conectors that came with my tower.

2.GROUND
3.MIC BIAS
4.?
5.SPK OUT R
6.?
7.?
8.no pin
9.SPK OUT L
10.?

I have two extra connectors labled RETURN L and RETURN R and am not sure where to put them. Let me know if I have put the others in the correct order and also where I should put the RETURN R and RETURN L connetors. Thank you

I have looked into it some more and am thinking that maybe FSENSE 1 = RETURN R and FSENSE 2 = RETURN L. Anyone know is this is correct?
