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.

  1. In alsamixer, disable "loopback".

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

    1. Opening a terminal and logging in as root

      sudo su

      (Or however you like to log into root.)

    2. 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

    3. Reboot.
