Replacement of pulseaudio by pipewire

My ctwm setup was clobbered when I moved to Fedora 37 because pulseaudio is
being replaced by pipewire, and I invoke pulseaudio both in .ctwmrc (starting up
audio) and in menus, e.g. invokin the pulseaudio control panel.

I wonder whether any other ctwm user has had similar problems, and if
you've dealt with them what changes do you have to make in the ctwm setup
facilties?

So far I have found very little information that's of any use to help me get
audio working in F37.
