My experiences are similar. I had it all working with Pulse + Jack a year ago, on a previous workstation build, but it was a massive pain to get there. I had my m-audio USB keyboard working, along with Tracktion Waveform and VCV Rack. (None of which give tolerable audio quality with vanilla Pulse, even on new Ryzen 5600 + dedicated Sonar audio card.) Based on the last experience, this time I'll take a snapshot of current .deb packages installed, a full copy of /etc/ and all my dot files (audio stuff seems to be spread far and wide under app-specific ~/. files as well as the expected places ~/.local and ~/.config). I recall even when it was working, occasional upgrades (albeit Debian unstable) would stop various components, and troubleshooting an audio stack, if it's not something you do regularly, is slow and frustrating work. Referring back to earlier configuration files and package names should make this easier. First step though is working out again why Debian still has jackd1 and jackd2 packages. The first search result for that question is from 2011, and it sounds like OSS / ALSA is the only reason jackd1 would be preferred. And there you have a fantastic example of how befuddling audio on GNU/Linux can be for the casual user.
