iTunes movies HD Rental advertised as 5.1 surround, but only plays in stereo "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?
This is a long-term issue for Windows 10.  I've seen problems with all 5.1 sound going back 18 months.  Most posts I've seen say to try this:


Go to your Windows Sounds settings
Under Playback, select Speakers and go to their Properties
Under Enhancements, deselect the Disable all enhancements checkbox
Activate the Enable Speaker Fill checkbox and click Ok


If that doesn't work, try this:


Go to the sound settings
Select your device
Properties =&gt; Advanced tab then select 24bit, 96000Hz from the dropdown
