@georgejolliffe Thanks for your reply.
But I can’t find any options to disable DTS in Plex Player settings on Shield TV. What I can get is to change the web player settings in the Shield TV IP’s Plex Media Server web console.
Home theater topology:
Sony TV
|-- HDMI – nVIDIA Shield TV
|-- HDMI – SONOS Beam
Update: I have already solved the transcoding issue of SONOS Beam.
That was really simple:
- open Shield TV
- open Plex
- setting – advanced – channel, just choose to disable it, neither HDMI nor Optical
- It would transcode DTS to AC3
Hope this could help someone who faced the same issue about SONOS Beam.
