No sound on Ubuntu 20.04

Question

I recently upgraded to Ubuntu 20.04. After reboot audio is not working. I tried to reinstall pulseaudio and alsa but still not working:

sudo apt-get install --reinstall alsa-base pulseaudio 
sudo alsa force-reload

Screenshot showing AlsaMixer

Still not working.

Before reinstalling pulseaudio, you have checked all relevent settings there, right? — Sim Son, May 30 '20 at 17:37
can you see what type of audio out you can find in settings?,line out or simmilar — trond hansen, May 30 '20 at 17:55

In alsamixer, disable "loopback".

I had the same issue.It helps to have something playing in the background while performing these steps. What worked was:

Opening a terminal and logging in as root
```
sudo su
```
(Or however you like to log into root.)
Edit the file found at /usr/share/pulseaudio/alsa-mixer/paths/analog-output-lineout.conf and change any instances of Element (such as [Element Desktop Speaker]) from switch = off to switch = on.
```
gedit /usr/share/pulseaudio/alsa-mixer/paths/analog-output-lineout.conf
```
Reboot.
