I definitely have both processes running.

I don't have pipewire-pulseaudio installed, but I have pipewire and pulseaudio
installed. Both are shown as automatically installed in "zypper se". Based on
/var/log/zypp/history they were installed during initial system installation
(2019-08-20 for one system and 2021-05-13).

I also have a third, older, system where libpipewire was (automatically)
installed at 2018-07-12, and later pipewire and some related packages
(pipewire-tools, pipewire-spa-tools, pipewire-modules and pipewire-spa-plugins)
were installed at 2019-05-23 (but again no pipewire-pulseaudio).

Note that pipewire is now installed from Packman, as that repo has higher
priority, but it wasn't from there initially.
