Player Version#: 7.22 (Apple TV 4K first Gen)
I ripped my GoT UHD Blu-rays to my Mac mini M1 which runs PMS. The episode have both the TrueHD Atmos and the compatibility track. The video is Dolby Vision with HDR10 fallback.
Then I play the episode with the compatibility track (AC3) the video will be displayed in Dolby Vision (Direct Play) when I choose the TrueHD track it falls back to HDR10 (Direct Stream).
Is this a bug or a limitation?
