Setup:

  Lenovo Gen3 X1 Carbon w/ Intel GPU
  Audio redirected via HDMI to a samsung TV
  Both Wayland and Xorg sessions

I manually set the audio output to the HDMI output in GNOME control
center. I thought it would remember my setting like it does for monitor
layout, but that does not seem to happen. It sounds like is supposed to
be handled by PulseAudio?

Likewise, when I remove the HDMI device, I would expect audio to be
redirected back to my laptop speakers.

Is it correct that this should be handled by PulseAudio and not by
something like gnome-settings-daemon/control-center?

What's the PulseAudio version?

What does "pactl list cards" show when you have the TV plugged in and
directed audio to it, and what does it show after unplugging the TV?
Close gnome-control-center when plugging out the cable - I've seen g-c-c
interfering with the routing during unplug events.

I'll attach two versions. First is connected and sound directed to TV.
Second is TV unplugged but before manually changing output back to
laptop speakers.

I've seen this too. I think it has to do with GtkTreeViewSelection
updating the "browse-mode" selection when displaying the sound settings.

Ok, so HDMI is on a different alsa card than analog output. That
explains why unplugging HDMI doesn't result in moving audio to the
analog output. We don't currently automatically reroute from one card to
another on an unplug event. This should be fixed, but I can't give any
timeline.

You also had some issue with remembering routing choices. Is it so that
if you route to HDMI and reboot, audio isn't routed to HDMI any more,
even if the HDMI cable stays plugged in all the time?

I haven't tested that (and it's a bit hard for me to test right now).

My problem is that I unplug the HDMI, go work in another part of the
house, and then come back and plug the HDMI back in. I would expect the
audio/video to be redirected as a pair (even though they are separate
sub-systems in implementation).

but there is no available HDMI ports available anymore , this mean that
the only available port is the internal speaker as headphone is not
plugged

Yes. What's the reason for stating this fact? If you had some point to
make, I didn't catch that.
