I still get this issue even on focal, or atleast the fix is the same. I have a USB headset and upon reboot it always switches to the USB headset regardless if HDMI was selected last. It's a desktop so things don't get unplugged.

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. [Test Case] 0. Plug in a monitor that supports HDMI audio (one that appears in your Settings>Sound) 1. Log out and in again. Verify the default audio device in Settings is still speakers or headphones. Not the monitor's HDMI audio device. [Regression Potential] The behaviour is changed back to what it was before 19.10, some users might find it inconvenient and prefer the auto switch but the feedback we got shows it's unreliable and an annoying for the majority of our users so we will got back to default to safest behaviour. The fix proposed just reverts to the same code used in PulseAudio 12 and earlier. It has also been released and verified on focal already.
