I have two HD Audio devices on our product computer. Intel HD Audio and Realtek HD Audio. I don't know why, but on my latest configuration both driver cannot be loaded. I didn't included the drivers on top of the answer tree in this build.
However, I ran dism /online /add-package to install winemb-inf-hdaudio and inf-hdaudss on the running system. But that didn't fix the problem.
What could be responsible for the driver load fail? Audio and Video engines are included, of course.
