Is 5.1 sound working for anyone? Tried "The Man in the High Castle" (which is listed as 4K/5.1 sound) and it played as stereo. Switched over to Netflix to make sure nothing got broken with the AppleTV iOS 11.2 update which I did just before installing the Amazon Prime app, and 5.1 sound was working just fine. Went back to Amazon Prime -- still no 5.1.
Any info on the subject appreciated, thanks!
5.1 isn't working for me either in the Apple TV App. Mr Robot is listed as 5.1 and plays as such through the Android TV app, plays as stereo through the Apple TV. 5.1 works generally on the device, so it looks to be a problem with the Prime App. Which given how long it's taken them to release is pretty ridiculous.
