From Gentoo Wiki
PipeWire requires the presence of a D-Bus session bus and an XDG-compliant environment. Both requirements should be met by a desktop profile; on such systems, starting PipeWire is as simple as running the pipewire binary. On other profiles, if using OpenRC, permissions requirements might also need the elogind USE flag on the media-video/wireplumber package, together with elogind itself.
