I am using Ubuntu 19.10 for few months. Suddenly voice output is not working. In-spite of trying reinstalling sound drives and tried all options despite that it is not working. Any inputs to it?

    I would boot a 'live' system (eg. Ubuntu install media and use 'try ubuntu') to confirm it's not hardware (ideally I'd suggest using something rather different to what you have installed, but even a 19.10 'live' would be useful). I've got a dying desktop that on rare occasions boots with 'dummy output' and in my case, it's components on their way to never working again (rebooting usually fixes it for me, but not always.. and it's the same for any booted OS whether installed or 'live') – guiverc Mar 19 '20 at 10:19

Adding to Andrea Pavan's answer:

You can first add the variable to a new boot session and check if it works

  1. Reboot your system. AT GRUB, choose Ubuntu and press E. You will be taken to command line options.

  2. Locate the line beginning with Linux. Add the following parameter at the end of the line snd_hda_intel.dmic_detect=0

  3. Press F10 to reboot.

After verifying this has indeed solved your sound issue, you can make this change permanently by performing the below steps

  1. Run sudo gedit /etc/default/grub from terminal.

  2. Locate the line beginning with GRUB_CMDLINE_LINUX_DEFAULT and append the above parameter to it. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0"

  3. Save and Close gedit.

  4. Run sudo grub-mkconfig -o /boot/grub/grub.cfg

  5. Reboot.

When I was stuck with the same issue, the below link helped me resolve it.

For > 5.3.0-40 kernels, try adding:

"options snd-hda-intel dmic_detect=0" in the /etc/modprobe.d/alsa-base.conf.

and finally reboot the system. This worked for me!

Sound works well with Kubuntu USB live. The cause of no sound being heard from speakers or headphones is because There is a problem with an error in the last update of the PPA with the Nvidia driver. They sent a filth as update and they have not solved it.
