Please reread my Comment #7. If by the service, you mean calfjackhost, then yes the service works. That quoted comment in my Comment #7 is from the developer sp1rit and a thread we had about calf. As far as we can tell, the only runtime requirement is libjack.so.0()(64bit), which is provided by both the jack and pipewire-libjack packages. And rpm figures that out on it's own, so there should be no need to explicitly require jack or pipewire at runtime. BTW, a user could install pipewire, without installing pipewire-libjack. So the real requirement is for the .so file. Gene
