Details

pipewire as a dropin alternative is getting more and more interesting - it would make sense for it to provide jack and libjack.so=0-64 so one can install many pro-audio packages without pulling jack as a dependency.
This task depends upon

"...install pipewire-jack-dropin or uninstall jack/jack2 to let JACK clients load the compatible libraries automatically."

See https://wiki.archlinux.org/title/PipeWire#JACK_clients

I don't see how this could possibly work since the libraries are in /usr/lib/pipewire-0.3/jack/ and they won't be found by ld.so without being explicitly pointed there at build-time using rpath, or at runtime using ld.so.conf (which the package does not provide).

Actually using this dependency provider would simply break every program trying to link to libjack...

Note the pw-jack manpage specifically points out that you use the pipewire-jack software by running pw-jack which "modifies the LD_LIBRARY_PATH environment variable so that applications will load PipeWire's reimplementation of the JACK client libraries instead of JACK's own libraries."

https://man.archlinux.org/man/pw-jack.1


Apparently it is possible to install as the system jack implementation too, which I think is what you actually wanted.

@Eli: Were you referring to the origninal query or my comment?

The ticket itself, not your comment.

alright, that makes sense! I just didn't find how to install pipewire as a system-wide replacement for jack.

It is currently not possible to use pipewire for hardware that relies on e.g. the FFADO driver stack.

While this setup is not super common but affects pro-audio devices, I would be much more happy with a solution that still allows both use-cases.

An intermediate package that introduces the required symlinks or modifies ld.so.conf (similar to how it is done in pipewire-jack-dropin [1]) and conflicts/provides/replaces jack would be much more flexible for the time being, as it will take some time for things to be fully compatible (if at all possible e.g. via ALSA drivers). The current setup allows people to check for compatibility or even attempt a hybrid setup, while still relying on jackd, which is able to use the FFADO driver stack.

As a short update to this topic:

I have created a new upstream project [1] which will allow us to devendor the existing tooling from jack1 and jack2. The effort is tracked in a ticket [2].
Afterwards I will change the pipewire build to have pipewire-jack provide jack.
