Does the sound device still disappear? I can't judge much from the given dmesg output whether the sound device appears at first or it's gone after some time by some reason. Meanwhile, the message about "init of i915 and HDMI codec failed" can be ignored in your case. It's a message merely indicating the lack of i915 graphics, and that's valid on your system (where it has only Nvidia GPU as active). In anyway, try to boot with the kernel in OBS Kernel:SLE15-SP4 kernel. And give the dmesg output as well as the alsa-info.sh output right after the boot with that kernel. -- You are receiving this mail because: You are on the CC list for the bug.
