Plex App on NEW Apple TV App Store

Most of my source material is DTS or DTS-HD and I have a receiver that can support pretty much whatever. I don’t understand the audio formats enough to know which setting provides me the best audio quality though. I presume it would be setting it to Dolby instead of Auto…

Well, bit trickier.

Currently, The DTS-HD will never be used, it’ll just use DTS-core track, aka, its just seen as normal DTS. As apple hates DTS, PMS just transcodes DTS into AC3 before sending to the ATV, so it would be treated by the ATV4 as an AC3 5.1 input. This assumes your PMS is on a device which can perform the DTS transcode in the first place.

There is new an option here for the Plex guys now that the ATV4 can take an EAC3 7.1 input, of having PMS transcode the DTS-HD track into an EAC3 7.1 track and using that, but I am making an assumption here that all the downstream code they need to do that exists and that EAC3 7.1 can be input over HLS. (how the data is transmitted to it by all methods other than direct play)

If you want your 2 channel stuff to stay 2 channel = auto
If you don’t care about 2 channel stuff, and have 7 speakers = auto
if you don’t care about 2 channel stuff, and have 5 speakers = flip a coin.
If you don’t care about 2 channel stuff, and want your 5.1 channel stuff to not go through a process to create 2 additional channels = dolby surround.
