HD Front Audio Pin Layouts Different in Case and MotherBoard

[booleanyesno]

The Pin layouts for HD Front Audio on my Antec 900 case and my GA-790X-USB3 motherboard are mismatched, although both have 10 pins and do not have the 8th pin (so they are physically connectable). The problem is pins 5,6,7,9,10 seem to mismatch.

Antec 900:
1: MIC2 L
2: AGND
3: MIC2 R
4: AVCC
5: FRO-R
6: MIC2_JD
7: F_IO_SEN
8: Key (no pin)
9: FRO_L
10: LINE2_JD

GA-790X-USB3:
1: MIC2_L
2: GND
3: MIC2_R
4: -ACZ_DET
5: LINE2_R
6: GND
7: FAUDIO_JD
8: No Pin
9: LINE2_L
10: GND

Is is safe to connect them?

Other than the different naming, they should be the same. Gigabyte, Asus, Biostar and others have a different naming convention, but they're all the same.

Yes, it is safe to connect them to the audio header on your motherboard. No problem! 😀
