Jack Audio application won't start under pipewire

in flag

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.

Has pipewire-jack been discontinued? Just tried to install it and it's not in the repository.

I have found a way to make this work, but it seems over complicated.

You need to start your app with

pw-jack your-app

This redirects libjack to the pipe wire version. This is highly unsatisfactory, and for example does not work with snap applications.

It should be a system wide selection.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
