Question asked by Vikneshwar Thandeswaran on May 13, 2018

I am using i.mx6ulevk with Linux L4.1.15 (shipped with board) . I want to record voice using on board Mic of the development board. I am using the command $ arecord -d 10 /tmp/test-mic.wav to record voice for 10 seconds and using $aplay /tmp/test-mic.wav command to play the recorder voice. The issue is  cant hear any voice in the recorded wav file.I checked the speacker section with some sample wav file its working well. so the problem is with Mic section . Help me to solve this issue.
