Pulseaudio keeps resetting after logout

Question

I had to set PulseAudio through pavucontrol since sound did not work. pavucontrol shows Dummy output as output device (??). So I went to

pavucontrol > Configuration > Built-in audio > Analog Stereo Duplex (unavailable)

and then it works fine (why is it showing it as unavailable if it works??). It also works with Analog Stereo Output (unavailable).

But each time I login, sound stops working, Dummy output appears again, and I have to set the thing... again.

Everything worked fine in Fedora 29, but never worked since I upgraded to Fedora 32.

How can I prevent PulseAudio from resetting?

I found these two answers that together fixed my issues:

https://unix.stackexchange.com/a/182294/149203

https://unix.stackexchange.com/a/462671/149203

These pages suggest to modify the file /etc/pulse/default.pa to get the modifications permanent, but my experience indicates that after a system upgrade this kind of modifications usually gives problems.

So I made the following bash script that fixed my particular problem:

 #!/bin/bash
 pactl set-card-profile 1 output:analog-stereo
 SINK=`pacmd list-sinks | grep 'index' | egrep -o '[0-9]*'`
 pacmd set-sink-port $SINK analog-output-lineout

The command

 pacmd list-cards | grep 'active profile'

allows you to check your active profile (Configuration tab in pavucontrol), while

 pacmd list | grep "active port"

shows you the active port (Output Devices tab).
