    Is Dolby digital though AirPlay only supported on the most recent Apple TV? On my gen 3 I’m getting the error ” an error occurred loading this content “.

      Wow, I’ll need to do some digging but I think Dolby 5.1 and 7.1 tests are only enabled for Apple TV Gen 4. In my own ignorance I didn’t even know you could Download the AV Aid Apple TV App unless you had a Generation 4 Apple TV. Very sorry about that. I’ll have to do some testing on Gen 3 and see what I can do about making sure that it at least warns you about that limitation.

        I think I may have miscommunicated a little. I’m using the iPhone app (iPhone 6s iOS 9.3) and I’m using the app through airplay onto my Apple TV (gen 3), I’m trying to use the 5.1 or 7.1 audio test when I get said error.

        I hope that clarifies things better.

          Okay cool. I’ll look into that use-case. My guess is that the Apple TV Gen 3 might not decode the Surround files.. But I don’t know if I’ve tried that yet.

          Hmm.. Do you know what version tvOS is loaded on your Apple TV? It should be in General>About> I tried it with an Apple TV Gen 3 (tvOS 9.2), with a fresh install from my iPhone 5s running 9.3.1, and it seemed to work fine. Also, where is that error message being displayed? (On the Apple TV screen, or on the phone?)

          Thanks for helping me locate the issue.

            I am running 7.2.1 (I tried to update and is says I have the most current OS).
            The error was on the Apple TV.

            Thank you for both your quick response and work. Even with this issue I’m found of you’re app.

    Thanks Dakota! Glad you like the app. I am so far, unable to recreate your error, but I will keep at it.

    Since I can’t recreate the issue yet, your responses are very helpful in diagnosing the problem.

    I just thought of something… There may be a setting inside of Apple TV (Audio & Video Settings) where you can change the Dolby settings. Can you check there and see if you need to switch something on?

      Everything seems to be set up correctly, unfortunately still no luck. I’ve tried power cycling all the devices I’m using as well.

      I think the issue is somewhere between my phone and the AppleTV, the AppleTV will not seem to receive the file I’m trying to play (5.1/7.1). Everything else works properly. The only other time I run into this issue where the AppleTV did not seem to want to receive my file type properly was when I was using an app (VLC player) and typed to play an MKV file over air play. That being said, I did manage to get it to work if I mirrored my iPhone.

      Which gave just me the idea to try that with 5.1/7.1! Interestingly, it did play the file while mirroring my iPhone. But it was not in surround sound. I imagine that issue is a set up issue on my part.
