VAR-SOM-MX6 DMic - Variscite Wiki 

I already read this document it is given that in alsamixer you have to set oversampling rate but i can not  find anything in alsamixer that can set oversampling rate. I'm using 4.9.11 kernel version.

Hello Ayush,

Alsamixer is always resampling all streams to default. Proper file for change this is ~/.asoundrc

http://www.alsa-project.org/main/index.php/Asoundrc

You can check result here: cat /proc/asound/card0/pcm0p/sub0/hw_params.

Regards
