Unable to record in mono with DAC+ ADC Pro

Hi all,

I am trying to record a wav file in mono using arecord

arecord -d 5 -D hw:2,0 -f S16_LE -c 1 -r 48000 /home/pi/test.wav

This however throws the error: arecord: set_params:1349: Channels count non available

When I set the channel argument to -c 2, everything works.

Is it possible/which settings do I have to change, to record single channel audio?

System:

RaspbianOS 64bit Bullseye

Kernelversion: 5.10.92-v8+

 

Best regards,

Felix
