Mine is almost the same, but...
I have mobo M2N-SLI. This is the same positions that the manual asked since the beggining. But in my mobo, there are some differences (it seems almost the same of yours, however mine is mirrored).
MIC 2 X X AGND
MICPWR X X +5VA
(blank) X X BLINE_OUT_R
NC X O
Line out_L X X BLINE_OUT_L
Any idea if there's something I can do?
