Ohh MM, what version Apple TV did you get, and how is it set/hooked up? Hopefully lots of great folks here can help you with figuring this out.So, I bought an Apple TV. Still no luck with Tidal which I understand from what other members have explained. But, I signed up for a Trial subscription to Apple Music and my results are the same i.e. I only get stereo. Still can't listen in 5.1.
