Windows 10: How can I get Windows 21H1 to stay on the Dolby Atmos for Home Theater, rather than...

I rebuilt my system drive onto a SSD because my HDD failed. I had been upgraded to 21H1 before the rebuild, but I decided to download a fresh install media for 21H1 and do a clean install. I pipe sound into my AV receiver 7.1 via HDMI. I use the Dolby Atmos for Home Theater. After a reboot, Windows always reverts to stereo. How can I get Windows to stay on the Dolby Atmos for Home Theater, rather than reverting to stereo after a reboot?

Dolby Atmos for home theater crashes - Creators Update

Hoped that the new fix in the newest MS update fixes Dolby Atmos for home Theater:

• Addressed issue where, after installing the Creators Update, audio output through external decoders no longer works.

But no.

Still with this Setup can't use it

Onkyo 656 Dolby Atmos Receiver

NVidia GTX 980ti with HDMI 2.0b connected at the HDCP HDMI 2.0 Port from the receiver

Of Course 5.0 Setup with Dolby Atmos Speakers.

Again: If I select Dolby Atmos for home Theater I get Dolby Atmos in the Dolby Access app. No Sound in other sources. Also I can't Switch back to 5.1 Setup, it crashes from now on. Only uninstall and reinstall NVidia Drivers work now with Standard 5.1 Settings.

It is clearly a MS fault - please fix that.
