I am not sure where to post this, I’m pretty sure this is not reproducible, so I’ll better post it here.
Rack freezes my Arch all the time, it can happen when I open a patch, when I open Rack itself, when I update my plugins. Sometimes I can just kill the proccess, but most of the time XFCE freezes completely, as well as keyboard and mouse stop working after a few attempts to open a terminal or switch to another TTY. Sometimes I can use Rack sometimes, but opening another patch can easily hang everything.
I’m still kind of a noobie in linux, so I’m not sure where to look and what to test. Right now I’m using realtime kernel, but I had this problem on vanilla as well. Tested different “audio” and “realtime” groups priorities and setting various memlocks in limits.conf, as well as unlocking it. Regarding audio I’m using Cadence, tried it with different bridges and settings, also tried starting jack via QjackCTL. “Realtime” option or number of cores in Rack doesn’t seem to affect this problem.
This is happening only with Rack, everything else is working fine, Reaper for example (native), FL Studio in Wine, any native game, any other app. Can anybody suggest what should I look for? I’m completely out of ideas now.
