“26.04.1 LTS (Resolute Raccoon)”
Afaik when you start jack or Renoise in Jack mode it’s calls to jackd2 libs are transferred to Pipewire and it’s still actually running through that system.
Not saying it’s good or bad, just to let you know.
This is the same for Fedora 44. PipeWire emulates Jack for applications that need it.
sudo dnf install pipewire-jack-audio-connection-kit
