despite being able to get DD+ Atmos from Amazon Prime on the Roku, I am only getting DD 5.1 on the Disney plus app. I saw a table on Disney plus website (I think) that said Roku SS+ will provide Atmos for Disney plus. Any ideas ?.
I am in the UK using it with a Samsung Q9FN and Sonos arc through an ARC connection
Thanks for the detailed response. I have now tried all three actions with no success. Given I get DD+ Atmos from Prime Video , I don't believe it can be the cables, TV or Sonos arc. It must be something with the Disney + app on the Roku Streaming Stick plus - maybe a UK issue. Not sure what to try next as I only bought the Roku to get DD+ Atmos for Disney plus. I've got the App on my Samsung TV but that only provides DD+ 5.1 .
