There is no sound when I do the test sound.
When I run the company’s own qt application, the following message appears.
Failed to open ALSA sound device for input plughw:1,0 (Device or resource busy)
When I do the speaker-test, there is a beeping sound from side to side.
speaker-test -D hw:tegrasndt210ref,0 -c 2 -r 48000 -F S32_LE -t sine -f 500
Can you tell me how to fix it?
