There are known issues with PulseAudio handling of profiles, see e.g.

https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/276 .

Ubuntu bug: 
https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1872970

I tried to ping Debian maintainers to solve the issue of firmware 
installation and mention all these kernel/alsa-lib/alsa-ucm-conf 
dependencies, so far no answer. We're really like to make sure everyone 
gets an "audio just works' experience instead of having to replicate the 
same experiments...
