[pulseaudio-discuss] Device fallback priority

I have 2 alsa devices in my system, card 0 is my Nvidia graphics card
for HDMI Audio output, card 1 is my internal onboard audio. I prefer
the HDMI Audio via my Nvidia card and setting this as default device
works just fine.

When I now add another audio device like via USB or Bluetooth, its
sink becomes default, and this is quite what I want, so this is fine.
But when I now disconnect this device again, the new default sink
always is my internal audio instead of the HDMI audio.

How can I get the system to fall back to my HDMI Audio after the
active sink gets unavailable? Can I set priorities manually in
default.pa or similar?

The modules module-default-device-restore, module-device-restore,
module-stream-restore and module-card-restore are loaded. If one of
these is supposed to do this job, does that need some manual
configuration? If yes, how?

I'm running Ubuntu 19.10 64-bit. I already deleted ~.config/pulse and
restarted pulseaudio to make sure there are no unwanted settings in my
pulse db files. The file .config/pulse/[id]-default-sink correctly
contains the HDMI sink in the format of the output below.
