must support HDA to function correctly. Please follow the instructions in our
manual and chassis manual to install your system.

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".
