In case it's helpful, I posted a bug about this (but, perhaps, incorrectly as an ALSA problem) with my Alsa and PulseAudio information: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1846290
Above, it was mentioned that perhaps this is regards to module-switch- on-connect. FWIW, when I was testing Fedora 31, it correctly picked my onboard sound controller rather than my HDMI monitors (which have an audio passthrough but no onboard audio capabilities/speakers of their own) from the start and never tried to switch the output device to HDMI. I have further noticed that when I try to launch games via Steam, they have no sound, even if I make sure line out is the selected sound output device in gnome-settings prior to launching Steam. I did not have this problem on 19.04, so I wonder if it's related? Any tips on how I can further investigate and maybe file a separate bug report if necessary? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1847570 Title: PulseAudio automatically switches to HDMI sound output on login Status in PulseAudio: New Status in pulseaudio package in Ubuntu: Triaged Status in pulseaudio source package in Eoan: Triaged Bug description: On my freshly installed eoan system I have two output devices: - HDMI/DisplayPort 2 - GK208 ... - Line Out - Family 17h ... When I login into the system pulseaudio always select the "wrong" one (HDMI) and I need to go to gnome-settings/Sound/Output Device and switch to "line out". This applies to every login/logout not just reboots. I would be good if it would remember this choice so that I have to do it only once. Or maybe (if that is technically possible) just output on both output devices by default - this would be even more user friendly for newbies who will have a hard time finding the right place to change this (or maybe have UI in the volume slider to select outputs if there are more than one? But anyway, my immediate concern is that it should just remember my choice :) Please let me know if I can provide more information. Happy to dig into code if needed but I will need some pointers.
