Is it possible to have Plex not Transcode the sound from some of my 4k files?
According to the Dashboard (of my Synology NAS based Plex Server) The 4k Video is being direct streamed but the Audio (TRUEHD 7.1) is be transcoded to EAC3.
Ideally, I’d like the audio to just be passed through to my Atmos Amplifier.
Amazon Fire TV devices do not support passthrough for TrueHD audio. It will be transcoded to a supported format.
Blu-ray discs with TrueHD audio also include an AC-3 5.1 audio track. If possible, choose the AC-3 audio. You still won’t get Atmos, but the audio will direct play instead of transcode.
