Matthew,
pipewire are two userspace systemd services -> pipewire and pipewire-pulse. Check that they are running, you can also restart them, if there is a problem.
You can also try the following to monitor the devices:
1. For the basic info on pipewire -> pw-dump 0
2. For the basic info on pipewire-pulseaudio layer -> pactl info
3. To list all available playback devices -> pw-cat -p --list-targets
4. To list all available recording devices -> pw-cat -r --list-targets
5. To see what devices are playing and how they are performing -> pw-top
6. To try that a sound can be played over a selected device -> pw-cat -p --target XX file.wav
7. You can also use pavucontrol to control the overall loudness, as well as the loudness of particular applications and which device they will use to play.
Just a long shot, but what if replacing the audio device while the system is running causes pipewire to still believe that the default audio is the one present when the services started and it redirects all the sound to it, leaving the new device silent?
I hope this will help you a bit.

Oh actually it is now just Firefox where audio doesn't work. Sound test
works fine, Chrome works fine, just Firefox is now silent. Whee. It's turned
up all the way in the Sound control panel.
