Hi,

We integrated TLV320AIC32x4 codec to OMAP-L138 Soc board. We are using Linux kernel 3.3.0 with driver of TLV320AIC32x4. Driver is successfully detecting.

But we are not able to play a wav file using aplay. When we are trying to play any WAV file using aplay, it is not enabling the DAC and file failed to play.

When we try to debug that using debugfs, it look like, it is only setting "LOR" ==> "LOR Powe" ==> "LOR Output Mixer". But after that there is no further Input / path / output configuration found. As per the driver it should enable the "Right DAC" via "R_DAC Switch". When it will enable "Right DAC", DAC will be enabled and it may start playing WAV file after that.

We are not able the get the cause, what we are doing wrong. What should we need to do to enable DAC.

I am attaching the debugfs log for TLV320AIC32x4 dapm, it may be helpful to understand the cause, which we are unable to get.
