The other day my sound stopped working on Ubuntu 18.04 desktop. I have no clue why. The sound stopped working overnight for some reason. After some research I found the below command to restart the sound service on Ubuntu:

pulseaudio -k && sudo alsa force-reload

All works now! Give it a try and let me know if it works for you. Follow me on Twitter @itprohelper

  1. Worked perfectly for me! I am running Ubuntu 20.04.2 on a Veriton M6610G
    the output from this command:
    /sbin/alsa: Warning: Processes using sound devices: 35252(pulseaudio).
