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!

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!!!!

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)
