Thank you for reaching out. Based on the data and steps provided, I have analyzed the issue and identify the root cause along with the required actions.
The “DMIC Mono Channel Select” has been updated to “DMIC Channel Select.”
For DMIC mono use, please configure the controls as follows:
amixer -c APE cset name=“ADMAIF3 Mux” DMIC3
amixer -c APE cset name=“DMIC3 Boost Gain Volume” 400
amixer -c APE cset name=“DMIC3 Channel Select” [value]
Where:
[value] = 0 for 'Left'
[value] = 1 for 'Right'
[value] = 2 for 'Stereo'
