May be some gnome-* package you have in your system has pipewire and|or
pulseaudio dependencies.

More, you might have apt configured to consider recommended packages as
dependencies... and this could prevent unistalling pipewire and|or
pulseaudio... If so, to change this you can edit

/etc/apt/apt.conf.d/00norecommends

to have:

APT::Install-Recommends "false";
APT::Get::Install-Recommends "false";

Recently I did a Daedalus + LXDE fresh installation. I have only alsa here
and no pulseaudio or pipewire here: having Install-Recommends "false", I could
uninstall pulseaudio (do not remember if pipewire was installed and I
uninstalled it...)

Also, I did an upgrade from chimaera: same result.

Seems you should be able to uninstall both...

I would investigate to find if some gnome-* package in your system has
pipewire and|or pulseaudio dependencies (also avoiding recommended packages
being treated as dependencies).
