pipewire takes HDMI into account, it'll be listed as its own channel in the list
of audio devices. Shouldn't be the source of problems in and of itself.

Something came to mind as I read you, however. Something I had forgotten, and I
am not sure if it matters for pipewire at all. The content of the machine-id,
file that freedesktop loves so much, may be used to generate the name of device
files. Meaning that if it is random or empty, your audio channel will change at
each boot. That was the behavior with pulseaudio. Another Poetterism that makes
things more complicated than it has to be.
