I have HP laptop. The sound disappeared after an update. I have tried solution1, solution2, solution3 , solution4. Nothing works. Moreover, I cannot open alsamixer "cannot open mixer: No such file or directory" I would really appreciate help. However, I am not an engineer so please keep it simple! Thank you!

Does this answer your question? [Ubuntu 18.04 audio disappeared after update](https://askubuntu.com/questions/1218041/ubuntu-18-04-audio-disappeared-after-update) — guiverc, Mar 20 '20 at 02:40
FYI: The duplicate link applies to 18.04 with HWE kernel, ie. same kernel & upper stack as 19.10 — guiverc, Mar 20 '20 at 02:40
@guiverc unfortunately this did not solve the problem either — koppuli kappilka, Mar 20 '20 at 06:38
@guiverc I am not sure if this is the same thing but this worked: Open this file sudo gedit /etc/modprobe.d/alsa-base.conf And then add the following line to it: options snd-hda-intel dmic_detect=0 I rebooted et voila!

PROBLEM SOLVED!

I did this: Open this file: sudo -H gedit /etc/modprobe.d/alsa-base.conf And then add the following line to it: options snd-hda-intel dmic_detect=0 I saved it, rebooted and sound works! This seems to the same solution as many of you suggested but I just did not figure out where to add this line... Anyway, thanks for everyone!!!!

You can see it by `man sudo`. See https://askubuntu.com/questions/632798/what-specific-bad-things-happen-when-gedit-is-used-with-sudo – Pilot6 Mar 26 '20 at 10:31

koppuli kappilka If you reinstall Ubuntu, don't install the Nvidia drivers because you will run out of sound again. I did a clean installation of Kubuntu install the Nvidia drivers and I was left without sound again

Had the same problem, found a solution here on askubuntu and it worked for me! Ubuntu 18.04 audio disappeared after update

tomas reported that after adding a boot parameter to grub, their audio was restored. https://askubuntu.com/a/1218063/718497

So to answer my own question. After a lot of digging I finally managed to get my audio working again. After finding this thread https://bugs.archlinux.org/task/64720 I tried temporarily adding the boot parameter snd_hda_intel.dmic_detect=0 by following this guide: How do I add a kernel boot parameter? to verify that it worked. It solved my problem, and I added the key permanently now, and the fix seems to persist after reboot.

Please upvote tomas if it helps. :-)

(I would've posted this as a comment, but my rep isn't 50 just yet)

thank you! I will try that first thing tomorrow. Soundless social distancing is sad — koppuli kappilka, Mar 19 '20 at 19:53
I think now I managed to do that , since the voice came back. — koppuli kappilka, Mar 20 '20 at 12:09
