Does anyone have a complete list of major streaming services that provide 5.1 audio on some titles supporting Roku devices, including what DD format each use?
The only streaming service with Roku I've found that shows exactly their 5.1 audio format in title descriptions is Vudu, many titles have listed 5.1 DD+ and some older titles have plain 5.1 DD.
I've successfully gotten 5.1 audio with my Roku Ultra 4640 using the optical port output to my older Denon receiver (DD format selected on Roku audio settings) from the following Roku channels so far:
Amazon Prime Video(5.1 unknown if DD+ or DD on some titles)
Netflix (5.1 unknown if DD+ or DD on some titles)
Vudu (5.1 DD+ and DD titles available on some titles)
Roku Channel (5.1 unknown if DD+ or DD on some titles)
Youtube (DD 5.1 on some videos)
Roku Ultra 4640R, Roku Streaming Stick+ 3810R
