xgimi horizon ultra with android tv

Hi,

First let me thank the dev(s) and users for making all this possible. I kindly ask for help regarding the following. I own a xgimi horizon ultra that operates on android tv 11 rt.3.10.319. I've got version 21 beta 2 running now that plays dolby vision. However there's no dolby atmos passthrough to my receiver. The projector is connected via earc with a active optical hdmi 2.1 cable. All the settings are correct by enabling expert mode and selecting passthrough etc. I did see something like audiotrack raw, android iec packer. This cannot be changed.

My pc running linux with kodi works fine except dolby vision.

Any ideas how I can get atmos and dts-x passthrough working properly?

Thank you.

And apparently there's a mislabel on the download site:

The fourth one (bottom left) should be labeled firetv, not regular android. I downloaded that one by mistake but to my surprise it's the only one that works..

The correct android nexus/omega version doesn't install or run proper.

it's a projector connected to my receiver.

Small update. Sideloading the official beta 2 apk from kodi results in a working dolby vision playback. Dolby atmos and truehd are still problematic. dts-hd and dts-x work however. This applies to the offcial and maverik version.
