Transcoding DTS to DD 5.1 on Apple TV4
I've seen references to this on the forum but wasn't able to find instructions. I want to watch movies on Plex running on the latest version of the Apple TV that have DTS sound. My TV outputs to my Sonos Playbar that can't handle DTS so I would like either Plex or Apple TV to transcode sound to DD 5.1.
Can someone explain how to accomplish this?
