re. old school jack2 then I'm clueless if it were pipewire(-jack) I would ask to switch (jack-)transport mode to "none" or "master" only, as PW's still finicky/bad in that regard... is very hard if not impossible to diagnose what's the issue when it's not quite reproducible. please, keep searching for a plausible pattern and tell what you may find. cheers Reply
