Hi,
The recording is normal, and there will be distortion when playing audio files. It’s like speeding up playback.
Play.sh
#!/bin/bash
amixer -c tegrasndt19xmob cset name='I2S2 Channels' 2
amixer -c tegrasndt19xmob cset name='I2S2 Playback stereo to mono conv' CH0
amixer -c tegrasndt19xmob sset 'ADMAIF2 Mux' 'I2S2'
