I'm thinking hard about replacing/complementing my shield TV in my home theater with a roku due to the lack of 5.1 audio on most android TV apps. I know you kodi/plex users can stream 5.1 audio, but it seems like every other app (Cinema Now, Netflix, Hulu, hbo...) can't stream in 5.1 while my Roku's seem to have the ability to stream DD+. I know the app creators aren't supporting 5.1 sound, but it makes the Shield a substandard streamer. Am I missing something? No, Dolby Pro Logic isn't good enough btw, not when other streaming devices are able to receive a 5.1 stream.
Don't blame Android TV. Blame the developers of the apps..
