rtkit could not set nice-level to -11: Permission denied
Version, Distribution, Desktop Environment: Pipewire 0.3.33, Arch, KDE Plasma 5.22.4-1
Description of Problem: Launching an application (tested ardour6, renoise and supertuxkart) with PIPEWIRE_DEBUG=2 reveals that rtkit cannot set the nice level to -11 despite me having put myself in the rtkit group and the audio group.
I'm suspecting that the lack of realtime priority is the reason for the occasional xruns (1 or 2 every 5 minutes) I've been getting.
