Recently i wanted to use some drums plugins with ardour. However I had a problem whit two of them (Drumgizmo and Geonkick). When I add them sometimes ardour crash with message
Failed to register port “Out 12(Geonkick)/audio_in 2”, reason is unknown from here
 20537 segmentation fault (core dumped) ./ardev
other times i get message in messagebox
 jack zombified
As I read in other post on this forum It could be probelm with jack settings when these are by choosing audio hardware parameters that your system is incapable of keeping up with but I don’t think that’s a case because I have a new computer (16gb ram, ryzen 7 8x3.7 GHz and GeForce RTX 2060 6GB). Maybe there is parameter that I missed and it’s important? I start jack server by qjackctl. Here are my settings
Maybe someone see any incorrect settings?
As a last resort i tried to compile ardour from source code (on arch linux) but it was the same. I had also the same problem on my previous computer so back then I was sure It’s hardware issue but right know I have no clue. Maybe someone had similar problems or have ideas what could be a problem? I would be very grateful. Thank U in advance sory if it’s something obvious
