in the meantime, the problem was resolved. Short story: After booting
the 4.x kernel for the first time, sound disappeared. I recently did a
factory reset in the BIOS, and sound re-appeared.

So yes, at this point, I also suspect that there is some problem with
the kernel, but why this seemingly happens only on upgrade, I don't
know.
