Does Sling stream in Dolby 5.1 on Apple TV?

[donawalt]

HI all, I just signed up for the free week of Sling TV, and downloaded the app on my Apple TV Gen 4. I previously verified that it can broadcast Dolby 5.1 through my Denon receiver to speakers, as it works with other apps, but so far it appears everything is streaming in stereo on Sling TV app. I watched shows that were 5.1 on DirecTV, I found a couple of movies that were stereo....I don't really see any configuration on the Sling TV for that. I have the Apple TV audio config to always use Dolby 5.1, vs. the Auto setting.

Do - am I doing something wrong or is the Sling TV app stereo only?

Thanks!
