Last week I cut the cord and I liked the Roku interface a lot and bought a stick for my upstairs and an Ultra for my family room that has a receiver. After installing the Ultra I noticed the audio only came out in Stereo to my receiver. I did some searching and even did a chat with Roku about this issue. I made sure night mode was off, Audio leveling was off, and I changed my Audio from Auto to the surround sound mode. After changing the setting I reset the box. I still can only get Stereo sent to my receiver no matter what app I use. My main app I use is Hulu and I know that sends in DD as if I use my Smart TV instead of my Roku it transmits in DD perfectly to my receiver. I have seen threads about this issue when Ultra was updated to I think it was 8.1, but I read mixed results on getting this fixed. I love the Roku interface but if I can get proper sound to my system their is not a point of staying with Roku. As I am not an Apple fan it looks like Amazon Fire will have what I need, but I can't say I like their interface that much. But I can get used to a interface if needed a long as the hardware works right. Thanks for any help.
