[Pkg-utopia-maintainers] Bug#984429: pipewire: could not set nice-level without rtkit

[Kevin Locke]

Package: pipewire
Version: 0.3.19-4
Severity: normal

Dear Maintainer,

With pipewire 0.3.19-4, if the rtkit package is not installed,
`systemctl --user status pipewire.service` includes:

pipewire[1455]: could not set nice-level to -11: No such file or directory
pipewire[1455]: could not make thread realtime: No such file or directory
pipewire-media-session[1473]: could not set nice-level to -11: No such file or directory
pipewire-media-session[1473]: could not make thread realtime: No such file or directory

After installing rtkit these messages disappear.  Presumably this also
avoids potential issues (glitches, etc.) under load, although I did not
observe any.

Perhaps it would make sense to add rtkit to Recommends for pipewire, as
done by pulseaudio?

Thanks for considering,
Kevin
