"The Revenant" is clearly labeled on the iTunes store as 5.1 surround. But after purchasing and playing the HD Rental (yes it was fully buffered) it only output in stereo on Windows 10.
The Netflix app outputs 5.1 surround correctly, and so do games, and so do 5.1 surround sound music downloads played through VLC, so I know my set up is correct.
Am I missing a setting? Also, can I get a refund?
