@Luigi: Yes, the pipewire devs do their best to make pipewire-libjack fully implement the jack interface provided by jack. The file libjack.so.0()(64bit) is provided by both, and either one works with calf as I mentioned in my email to packman. So you could let rpm check for the so file, and just remove the runtime requires for jack. Also, my openSUSE credentials don't work to download the package you want me to test. Do I need to register with pmbs.links2linux.de to download it? Gene
