I know we can use AirPlay to stream to the Apple TV, but native RAAT support would be amazing! The Apple TV is a relatively affordable streaming device and less noisy than a Raspberry Pi. While I realize this is a niche request, I’d love to use it for multi-channel audio streaming.
What’s interesting is that the Infuse app on Apple TV can bypass Apple’s resampling, so I expect the Apple TV could potentially be used as a “bit-perfect” multi-channel RAAT streamer.
Given it’s up to device manufacturers to want to integrate Roon Ready and they implement it themselves, I doubt you will ever see it as this isn’t Apples bag. Roon don’t add it to devices.
I believe that creating a Roon Bridge app for tvOS based on their existing macOS Bridge and iOS Remote app codebases shouldn’t require too much development effort. However, I do see the potential drawback of releasing a tvOS app that serves only as a Bridge without additional features.
