Dummy Output issue in Ubuntu 18.04.2 LTS

Asked by Pushkar Nagle on 2019-04-06

I am using HP 14Q CS-0009TU and Ubuntu 18.04.2 LTS. While watching a movie, the sound suddenly got muted and then I am getting 'Dummy Output' as my sound device.
I have tried all commands in this tutorial: https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-in.html
Tried everything, restarting alsa and pulseaudio, but no luck.

ALSA information is located at http://alsa-project.org/db/?f=19e97ca614c5b7467ad157876d40742e47aeca8e
