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. > Close gnome-control-center when plugging out the cable - I've seen g-c-c > interfering with the routing during unplug events. I've seen this too. I think it has to do with GtkTreeViewSelection updating the "browse-mode" selection when displaying the sound settings.
Created attachment 124083 [details] with audio directed to TV via HDMI
Created attachment 124084 [details] with tv/hdmi disconnected but sound has not been redirected to local speakers
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).
