Hi!

Fun with audio:

aplay works ok... as long as I don't use touchscreen. Touchscreen
sound results in

user@devuan-droid4:/my/unicsy_demo$ aplay -D plughw:CARD=Audio,DEV=0
/usr/share/unicsy/tones/fallback.wav
aplay: main:852: audio open error: Device or resource busy

I guess that's usual "alsa can be only opened once".

Okay, so lets try to use paplay... That works, but audio quality is
bad, with loud clicking perhaps once a second.

Linux devuan-droid4 5.10.4 #1 SMP PREEMPT Mon Jan 18 21:56:35 UTC 2021

Best regards,
