DTS sound playback

I use Apple TV 4K and I have an Infuse Pro subscription. My problem is that I cannot listen to DTS format material. What should I set to solve this problem?

Unfortunately dts is converted to LPCM by the ATV4K and then sent to the receiver/ processor. At the moment, DTS won’t be passed directly to your receiver


Ahh thats an interesting point, I wondered why my receiver wasn’t showing the DTS flash screen anymore since I got Apple TV but the audio was still showing as 5.1. In fact im not sure it shows for DD either since but the surround has always sounded great.

So what is LPCM then when talking about a surround signal, does that mean that DTS audio is still surround after converted?

EDIT: Seems like it’s pretty well explained here
