So, upgrading to #Debian 13 #Trixie broke my audio setup.
What I could find out so far:
There's an issue in the alsa-ucm-conf package (https://github.com/alsa-project/alsa-ucm-conf/issues/559) introduces in version 1.2.14 which breaks support for the Focusrite Scarlett 18i20 audio interface somehow.
Sadly that is the version that ships with Debian 13.
I'm open to ideas because I'd really like to have music again.
