I'm new to this forum so sorry if this has been answered before. I've had 2 roku products , a roku 2 and now a 4k stick and on both the show vikings is only detected and out put in stereo. I also have a amazon fire TV and on that its output rightly as 5.1 . Other shows ie Lucifer on prime outputs rightly as 5.1 . So can anyone shed light on my issue? Thank you in advance.
Make sure your Roku is set to auto-detect or DD+. I have no problem on my 4210 and Sony AVR with that title on Amazon (other than my Sony hissing on the "ssses", but that's another story...). If your AVR truly does not support DD+, then Dolby Pro II with PCM is almost undectectable in "blind" tests.
Edit... don't use a splitter device either.

Thank you for your suggestions, my avr is a Sony dn 850 and supports dd+ . As i said in my earlier posts, it supports it fine with an Amazon fire TV streaming stick and with the roku it picks up other shows on prime in surround, just not Vikings. Sure it must be something to do with the signal generated not being picked up with the roku, but don't know how or why!
Again thank you for suggestion but had the same issue with my older roku 3 as my new roku streaming stick. Same issue when watching 'grand tour' but only season 2 , season one plays surround ok! . So makes no sense to me why roku (either model) has an issue playing surround on some programmes and not on others. Don't have the problem with other apps like Netflix, thats has always played surround just fine. Guess for continuity of sound with prime i will have to stick to my Amazon fire TV or watch it through the TV itself.
