After looking through the posted bug and comments I'm not sure that the
issues are related. It seems more like, in this case, GNOME is just out
of sync with pulse about what the default device is thanks to pulse
changing it out during login. Changing the selected device fixes the
issue (until the next login).

Title:
Default audio device changes on reboot; audio still outputs using my
previously-selected device
Status in pulseaudio package in Ubuntu:
New
Bug description:
This is present in Ubuntu 18.04, 18.10, 19.04, and 19.10 daily build.
It was not present in Ubuntu 16.04.
I have a USB microphone which also appears to pulse as a speaker.
Pulse keeps picking it as the default audio device. I can switch audio
devices to my analog line out, which works as expected until I reboot.
After reboot, my audio device switches back to the USB "speaker", and
Gnome shell / Gnome settings volume control adjusts the USB speaker
volume. Despite seeing the USB device as the current output device, I
still hear sound from my line-out.
In the interest of narrowing down this bug, I have found that
disabling "module-switch-on-connect" fixes the problem (my line-out
stays as the default audio device and I hear sound).
