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

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).

connect them for the AC'97 audio panel.
