Apple tv4 7.1 surround not workin

BEfore I begin, I know my audio 10000%.

THjs his is ridiculous that Apple TV 4 cannot stream 7.1 surround. I tried so many movies on iTunes and netlfix. Only plays in 2 channels, when I go to settings on Apple tv and click surround setting and take it off auto and select Dolby it plays in 5.1 surround even though it's a 7.1 movie.

Apple TV had this same problem before with Netflix and 5.1 audio and same thing now with 7.1. Only reason I bought this is because of 7.1. I'm returning it.

Its not my brand bew 2000k Yamaha receiver and nothing else. I leave my receiver in straight mode and it plays whatever codec it gets. It's funny because in auto surround mode on Apple TV it displays 7 speakers but plays 2 speakers. When I manually change it to Dolby surround on my Apple TV it will just play regular 5.1 Dolby digital and not the 7.1 Dolby digital plus.

MY old Apple TV works with 5.1 fine, my rocky 3 works with Dolby digital plus 7.1 when streaming Netflix. My blue ray plays all 7.1 discs perfectly. I repeat it is not my system it's the Apple tv4.

I Will be shocked if anyone has 7.1 speakers and their receiver displays Dolby digital plus and all seven speakers work. This is a joke. $200 for nothing.
