Det var pga. indlægget på reddit, at jeg opdagede det. Jeg har svaret længere nede i tråden.
Jeg tjekket vha. videokonsollen på Apple TV 4K og fundet følgende:
- I can only get Disney+ to output 5.1 while Apple TV 4K is paired to HomePods (see picture:
https://www.flatpanelshd.com/pictures/IMG_2767.jpg ). Better than before but Atmos doesn't seem to work yet – at least not for me. I'm running latest public version of tvOS on Apple TV 4K and HomePods.
- Checked same Disney+ title with LG G1's internal speakers. Here, Disney+ Dolby Atmos works as intended.
- Cross-checked with Apple TV+ and Netflix. They pass Dolby Atmos to HomePods as intended (see pictures:
https://www.flatpanelshd.com/pictures/IMG_2768.jpg and

I konsollen fremgår 5.1 lyd som 6 kanaler, men Dolby Atmos fremgår som 16 kanaler under 'channels' ude til højre.
