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'
amixer -c tegrasndt19xmob sset 'I2S2 Mux' 'ADMAIF2'
amixer -c tegrasndt19xmob cset name='x Auto-mute Switch' 0
amixer -c tegrasndt19xmob cset name='x LO DAC Playback Switch' 1
amixer -c tegrasndt19xmob cset name='x LO Driver Gain Volume' 70
amixer -c tegrasndt19xmob cset name='x LOL Output Mixer L_DAC Switch' 1
amixer -c tegrasndt19xmob cset name='x LOR Output Mixer R_DAC Switch' 1
amixer -c tegrasndt19xmob cset name='x PCM Playback Volume' 30
amixer -c tegrasndt19xmob cset name='x PGA Level Volume' 90
amixer -c tegrasndt19xmob cset name='x ADCFGA Left Mute Switch' 0
amixer -c tegrasndt19xmob cset name='x ADCFGA Right Mute Switch' 0
aplay -D hw:tegrasndt19xmob,1 /home/nvidia/audio/shapeofyou.wav

Run the Play.sh script.

Hello!

Apologies for the delay. Can you try …

$ amixer -c tegrasndt19xmob cset name='I2S2 Playback mono to stereo conv' COPY
