I was using CubicSDR on my Debian/testing machine successfully for some time. However a few months ago it stopped detecting the audio device. I have filled the Debian bug report https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1084177 but got no answer up to now.
All other applications are working correctly (either using audio via alsa or via pulseaudio or via pipewire).
I have run
( strace CubicSDR ) > /tmp/strace.dump
Attached is the result. CubicSDR tries to access the audio device via alsa, pulseaudio and pipewire, but for certain unknown reason all those attempts fail.
