microphone test for MCIMX6DLAICPU2

[abhirupmitra]

hi ,

I am unable to record form microphone in MCIMX6DLAICPU2. I used arecord command to record from mic but unable to play using aplay command.

I dont know how to use amixer alsamixer and I followed the instructions in the given link:

https://community.nxp.com/thread/351978 

but still didn't get any help out of that. The codec which is there in board is CS42888 and the alsamixer is detecting the chip.

Let me know if anything has to be enabled in yocto BSP.

Please help me out in this.

Thanks

Abhirup Mitra
