A workaround exists:
--------------------
* Add "options snd-hda-intel index=1" into /etc/modprobe.d/alsa-base.conf
* Restart OS
* When login screen appears, sound works ✔️. Actually the device "Speaker - HD-Audio Generic" is used instead of "Speaker - Family 17h HD Audio Controller", but sound works well.
* When I login, sometimes sound stops working ("Dummy Output" again), but then it's enough to run "pulseaudio -k" (pulseaudio is restarted) and I can hear sound
