[S905X4] Nokia 8010 : AVR not processing atmos data

Hello everyone,

I’m currently having trouble with my CoreELEC setup. My Marantz AVR is not picking up atmos data when playing TrueHD / EAC-3 atmos mkv.

Currently, my setup is
CoreELEC > Marantz > LG TV

When the AVR is on, it only shows TrueHD / DD+.
When it’s off, audio is sent to my LG TV and the Atmos logo shows up on the screen.

If I plug it this way
CoreELEC > TV > AVR through hdmi
My AVR picks up atmos but the sound is stuttering.

I also have an Apple TV 4K plugged directly to the AVR and when I play atmos content it does shows “Dolby Atmos” on my AVR. Same thing when playing Atmos content directly on the TV with audio sent to AVR through hdmi.

I’ve tried switching HDMI cables, every passthrough options are enabled in CoreELEC.

Does anyone know how to fix this ?

Thanks !
