Ubuntu 19.10 no sound

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!

Solution 1:

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!!!!

Solution 2:

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

Solution 3:

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. :-)
