(In reply to Takashi Iwai from comment #1) Thank you, Takashi. Sound works perfectly after executing the following commands: sudo zypper addrepo --priority 97 http://download.opensuse.org/repositories/Kernel:/openSUSE-42.3/standard/ Kernel sudo zypper dist-upgrade --repo Kernel Then I needed to reboot, and disable secure boot in my BIOS. >From my perspective, you may close this issue now, although I would be happy to report any further information that might be useful.
