Hello,
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.

Thank you and best regards,

The short answer is: You can't achieve what you want, at least not
by tweaking the configuration.
What you could try to do is write a script that catches default sink changes
(for example by parsing the output of "pactl subscribe") and switches to
HDMI
when necessary.
The feature you are requesting is one of the things that we plan to
implement.
We need to remember the user defined default sink when one of the routing
modules changes the default sink so that we can fall back to the
original sink
once the temporary default sink disappears.

Georg
