Hi experts,
       We are also working on getting the audio work with the same codec
tlv320aic3x
(TLV320AIC3106) with AT91SAMAD34 board. Playback is working fine with the board.
But we have issues with capture. On "arecord" , nothing is being recorded in
the file.
Can you please tell us the TLV320AIC3X register settings that has to be to
make the capture work.

Thanks in adavnce,
Dhiv.
