I have installed some month ago on a Dell Vostro 7590 elementaryOS 5.1. Everything works fine until something now has destroyed the sound. I can't see any audio device in the sound settings anymore.
Today I booted the elementaryOS 5.1 install USB-stick and there the sound still works fine. Both sound devices (HDMI sound, built-in sound device) is shown.
Can anybody help? I already searched through the web but don't find a solution how to activate the original sound driver...
Thanks in advance!
UPDATE: I now found this https://superuser.com/questions/1509312/sound-stopped-working-after-upgrading-to-linux-5-4-intel-hd-audio/1509313#1509313
But I'm not sure whether this agood solution for my case or probably damage anything.
