@Marcus: I sent the following email to packman at links2linux.de on August 17, but I've never seen it on their mailing list. **** Begin email text. "I've taken a look at the spec file for calf (http://packman.jacobs-university.de/suse/openSUSE_Tumbleweed/Multimedia/src/calf-0.90.3-3.17.src.rpm) at for some reason they add an explicit Requires: jack, even tho rpm figures libjack.so.0()(64bit) (provided by both jack and pipewire's jack dropin) as a dependency out by itself." I forced installation of calf without jack, but with pipewire-libjack-0_3, which provides libjack.so.0()(64bit), and calf works correctly. This includes calfjackhost and working as a plugin source for easyeffects. Would it be possible to remove the explicit requires for jack, and require libjack.so.0()(64bit)? Thanks, Gene **** End email text.\ What did I do wrong? Thanks, Gene
