I am using Linux kernel 3.0 and a Logic PD DM3530 SOM LV, looking for the amixer commands to turn on / off analog microphone bias supply.
Following lines do not have the bias needed for Headset MIC input:
amixer set 'Analog Left AUXL' nocap
amixer set 'Analog Right AUXR' nocap
amixer set 'Analog Left Main Mic' nocap
amixer set 'Analog Left Headset Mic' cap
Anybody can help?
