I did some further testing and it is definitely a Intel driver issue.
The Monitor does provide correct edid data. There is no need to modify it. I have installed a 8 year old AMD GPU and Audio over HDMI works instantly. WIndows automatically installs the correct drivers and HDMI is automatically selected as output device. It just works auto-magically.
Nvidia and AMD GPU'S are able to output audio over HDMI just fine, so neither the monitor, nor the cable are a problem.
I have also tried a dozen different intel GPU drivers. Not a single one works.
I also tweaked around BIOS settings, as some posts indicated changing CSM or FastBoot.
But nothing except Intels drivers are a problem here.
It's so sad, this problem has been around for years now without ever having been addressed.
