Jack audio server won't start

English Multimedia
1

I use the Reaper DAW for audio editing. About a year ago I reinstalled TW and jack audio was working with Reaper. Before that it would only work with alsa. The main advantage of this over alsa, is that jack will share audio with other apps. A couple of months ago I reinstalled TW and Reaper would no longer work with jack and only with alsa. Another symptom is that the jack server will not start because it can’t find any audio devices. If I choose jack in Reaper, it doesn’t see any input/output devices.

I tried to install pipewire-jack with zypper and got the following error:

“pipewirejack conflicts with libjackserver0” and zypper gave the following solutions:

Problem: 1: the to be installed pipewire-jack-1.2.7-1.3.x86_64 conflicts with ‘libjackserver0’ provided by the installed libjackserver0-1.9.22-4.2.x86_64
Solution 1: Following actions will be done:
deinstallation of libjackserver0-1.9.22-4.2.x86_64
deinstallation of libjacknet0-1.9.22-4.2.x86_64
deinstallation of libjack0-1.9.22-4.2.x86_64
deinstallation of jack-1.9.22-4.2.x86_64
deinstallation of alsa-plugins-jack-1.2.12-1.4.x86_64
deinstallation of pulseaudio-17.0-4.5.x86_64
deinstallation of pulseaudio-module-bluetooth-17.0-4.5.x86_64
deinstallation of pulseaudio-module-gsettings-17.0-4.5.x86_64
deinstallation of pulseaudio-module-jack-17.0-4.5.x86_64
deinstallation of pulseaudio-module-x11-17.0-4.5.x86_64
deinstallation of pulseaudio-module-zeroconf-17.0-4.5.x86_64

If I uninstalled all of these packages, I had no audio at all. Can anyone tell me why the jack server won’t start or see any audio devices on my system?

I think that is normal given that it wants to replace PulseAudio. However, it’s not clear from your opening post that Pipewire is installed. I would start with checking that environment first. I would remove PulseAudio and use the ‘pipewire-pulseaudio’ compatibility package instead.

FWIW, I’m using Leap 15.6, and have PipeWire, with ‘pipewire-pulseaudio’, ‘pipewire-jack’, (and supporting packages) installed. My sound environment is reported like this…

Thanks for your responses. I’ve got jack working now after a reboot. I’ll remember with future installs to remove pulseaudio if it’s part of the default install.

Anyone know the reason why the TW devs install pulseaudio?

A fresh Tumbleweed installation only installs pipewire and pipewire-pulseaudio for already quite some time. If you can reproduce the automatic installation of pulseaudio on a fresh Tumbleweed, you might want to open a bugreport. This shouldn’t be the case as far as i know.
