After I did a fresh install of LEAP 42.3, I realized I did not have functioning audio. I installed PulseAudio Volume Control a couple days ago. I presume the system recognized the sound card back then since I could select the correct Output Device in the Volume Control window, but no sound came out of the speakers or headphones when plugged in.
I googled solutions, followed some forum threads and suggestions from around the web, but to no avail.
Then this morning, I booted put up the computer and the sound was working!
Then a little while later, not sure what happened, I logged back in and the sound was gone. Now, Yast and PulseAudio Volume Control no longer recognize the Hardware Output Device. All I see is the “Dummy Output” and neither seem to recognize the sound card.
I believe it has something to do with ALSA, but I’m not sure. I ran /usr/sbin/alsa-info.sh

I didn’t see a place to edit the post above… so if I’m double-posting / breaking your forum etiquette, my apologies.
I have managed to get my machine to boot off an USB drive of Ubuntu 18.04, and I do hear sound out of the speakers, so that leads me to believe the original installation of openSuse had something go wrong.
So how do I go about reinstalling the kernel on openSuse?
If that doesn’t work, I may try reinstalling openSuse all together…
A kernel re-install can be forced in YaST > Software > Software Management … and under search type “kernel” and click on the black check mark icons next to ‘Kernel-default’ , and possibly also ‘Kernel-firmare’.
I can’t recall if you simply need ‘update’ or ‘update-unconditionally’ but a bit of trial and error will let you know that. (right clicking will show the options).
Ensure it is an upward green arrow you get.
Make certain it is NOT a red ‘x’ nor a ‘lock’ symbol. <<<< this is important !! You don’t want to uninstall your kernel, nor prevent future kernel updates.

I ran into a similar issue with that same intel device on an HP laptop a
week or so back but this was after an update to a working TW system. I
had sound working somewhat (no volume control and only from Firefox, KDE
setup showed no sound device). Problem fixed itself a couple of days
later after another update and plugs right along now so I just figured it
was a temporary glitch in the software/firmware.
