So, since I was running 18.04 I figured I'd get up to date since 18.10 is
getting end of life.

So, on my desktop I did the backport purge and then did do-release-upgrade
twice. And I now have a working desktop on 19.04. No errors, smooth
upgrade. Sound works as before. Cool!

But (you knew there was a but, right?), did the same on my laptop, no
errors. But, no audio devices, the PA Volume control shows only a dummy
device on the Output Devices (though, I get an AudioIPC Server on the
Playback tab when I play from say YouTube in a browser and it shows sound.)

JACK won't start, UBS Controls does not complain about anything.

Audio worked fine with with 18.04 and the UBS Controls backport...

Where do I look for clues?
