Windows 10: Dolby atmos for home theater, audio dropout issue

My settings are. Windows 11 pro. Gpu : zotac 4090 amp AIRO, hdmi from gpu to LG evo c4, then earc to my Sonos arc + era 300x2 + sub G3. Play using Dolby atmos for home theater, regardless of YouTube, or any audio video file. Audio dropout issue, it’s like it has some lag, or the sound volume will get incredibly low for like 1 seconds and come back again. Anyone encountered same issue like me, and any solution?

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.

click dolby atmos for home theater, it jump to OFF.
