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.

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 |

It solved my same symptom by appending following line
options snd-hda-intel index=-2
into file /etc/modprobe.d/alsa-base.conf, and rebooting.
