Jack applications are refusing to make sound. For example, trying to sart the SuperCollider server gets the error ATTENTION: The playback device "hw:PCH" is already in use. Please stop the application using it and run JACK again

This worked fine until recently on Ubuntu 22.04 LTS

There is a new(?) package required for Jack apps, pipewire-jack

sudo apt-get install pipewire-jack

You may need to reboot pipewire before this will work.

systemctl --user restart pipewire-media-session

This should fix it.
