Pulseaudio is currently set to "daemonize = no" by default and it should also 
be set "autospawn = no", in order for Plasma to use pipewire instead of 
pulseaudio.   Pipewire is the new audio solution, which is meant to satisfy 
use cases previously addressed with pulseaudio and/or jack, although it should 
co-exist and work with both regardless.

As I understand it originally udev would probe, auto-detect and hotplug 
devices, calling pulseaudio to process audio.  I am not up to speed how 
pipewire now interacts with pulseaudio in depth, but I can see on a Plasma 
system which has pulseaudio installed, pipewire is launched and uses pipewire-
pulse.conf:

                  \_ /usr/bin/wireplumber
                      \_ /usr/bin/pipewire
                      \_ /usr/bin/pipewire -c pipewire-pulse.conf

I have audio working, but no pulseaudio process shows up.
