Completely broke 5.1 audio. Only getting Multi-In audio codec on my Denon 3800 since the update, unless I force Dolby 5.1 in the audio settings. But, by doing so I lose the ability to have the Apple TV auto detect Dolby Atmos. Current setup is ATV 2nd Gen > Denon 3800 > LG C3. I’ve reported the issue to Apple, they agree something is wrong but cannot resolve it without a software fix.
Ive tested this with a number of movies on HBO Max, Netflix, Hulu, and Prime Video. My Firecube G3 and Shield Pro are outputting Dolby Surround, but the Apple TV outputs Multi-In on the same movies. The odd thing is I can still achieve Dolby Surround if I turn “audio descriptions” on. I also get Dolby Surround on movie trailers. The second I turn a movie on, Dolby Surround is gone.
It was broken on the 3rd gen 4K but 17.2 Beta 3 fixed it. I don’t have the beta on the 2nd gen 4K though, I don’t run betas on that one. The 1st gen 4K is also working correctly with 17.2 beta 3.
This should be fixed in the lastest beta (beta 3). Are you completely sure you are on the latest release?.
Question? Why would you put a beta on your everyday streaming device?
