Ubuntu 18.04, dummy output and sound disappeared.


Hello.

I have a problem with sound on Ubuntu 18.04.3 LTS, KDE.
Sound disappeared completely.

My sound devices disappeared in phonon and pavucontrol, and "Dummy output" appeared instead.
I tried everything i was able to find and nothing work out.


Please help

Did the sound work before (with Ubuntu 18.04.3)? If yes, what changed (any updates, BIOS updates)?
If you run lspci does it detect the audio device:
Code:
sudo lspci -vv | grep -i audio
Also look at dmesg:
Code:
sudo dmesg | grep -i audio

Yes, sound worked. I did some daily updates, but I don't remember, what was updated before sound disappearing.
It happened once before, but I restored sound by command
Code:
 
sudo alsactl init 0
sudo alsa force-reload
It worked out one time, but after next reboot, sound disappeared and nothing helped.

Just my first post wasn't published so long, that I thought, it was rejected by moderator due to wrong topic.

After reboot sound disappeared again, so, I found new solution:
in /etc/pulse/default.pa
I wrote
Quote:
load-module module-alsa-sink
load-module module-alsa-source device=hw:0,2
And restarted pulseaudio
