1. High Definition Audio supports Jack Sensing, but the panel wire on the chassis must
support HDA to function correctly. Please follow the instructions in our manual and
chassis manual to install your system.
2. If you use an AC'97 audio panel, please install it to the front panel audio header by
the steps below:
A. Connect Mic_IN (MIC) to MIC2_L.
B. Connect Audio_R (RIN) to OUT2_R and Audio_L (LIN) to OUT2_L.
C. Connect Ground (GND) to Ground (GND).
D. MIC_RET and OUT_RET are for the HD audio panel only. You don't need to
connect them for the AC'97 audio panel.

and adjust "Recording Volume".
