Front audio on Biostar M7NCD pro?

I have the Biostar M7NCD pro MB in a Powmax case. The case has front audio
connectors. I was going to enable them but on the MB there is a front audio
header that looks like the wires should go to but has jumpers on it and in
the Biostar manual, the labeling doesn't match. The case has:
2 mic ins,
2 ground,
left in.
left out,
right in
right out.

The MB audio header has:
mic in
ground
mic power
audio power
right out
right out
left out
left out.

I know Biostar has crap for tha manual. is the 2 right outs and the 2 left
out an misprint in the manual?
