I have the new Ultra 4661R connected to a new Sony STRDH590 Receiver and the Receiver connected to a new Sony XBR 65X900F TV. When using Roku, regardless of what I am watching the receiver Display says PCM. I have tried movies on Roku Amazon Prime, Vudu, etc and always shows PCM. I can watch the same movie on Amazon Prime on the Sony Android TV Amazon Prime app and it shows DD. I have tried every setting in the Ultra Setting Audio and nothing changes. My other devices (Tivo and XBox) connected to the Receiver work fine and display DD. Am I doing something wrong?
The manual for the Sony STR-DH590 says it does support Dolby Digital Plus and outputs it as 5.1. Everything from Roku Ulta displays Linear PCM as input from Roku on STR-DH590 Display
