For recording, i am using this command on iMX8M

arecord [-Dplughw:0,0] -r 44100 -f S16_LE -c 2 -d 5 record.wav

 

Output : 

root@imx8mqevk:/home# arecord [-Dplughw:0,0] -r 44100 -f S16_LE -c 2 -d 5 record.wav
ALSA lib ../../../alsa-lib-1.1.4.1/src/pcm/pcm_dsnoop.c:638:(snd_pcm_dsnoop_open) unable to open slave

arecord: main:828: audio open error: No such file or directory

 

Before this we need to set amixer to enable microphone. But I don;t know how to set it up for iMX8M.

 

can anybody help me on this ?
