How can I force the Plex-app on NVIDIA Shield TV to always transcode audio for anything except AC3 and DTS when using HDMI-passthrough? The option is there on the regular Plex-app on e.g. my phone, but the Android TV-version of Plex doesn’t show anything such. Why does the Android TV-version not have such an option in the first place, when Plex is very clearly capable of transcoding the audio? Before you ask: yes, I do want to use both HDMI-passthrough and yes, I do want any audio-codec except those two codecs to be transcoded. No, I do not want video transcoded. ---

Set passthrough = optical in Plex app settings. Then select AC3 and DTS in the codex options that will appear next to the passthrough setting. ---

Plex app version? What happens when you play TrueHD, EAC3, etc audio? You can also try disabling audio codecs in the Nvidia Shield audio settings. ---

Some Reddit-posts also said that doing what you suggested should work, so out of a hunch, I powered my whole setup fully off for a bit and it appears to be working now. I guess something was stuck or something? Anyway, I am very much satisfied that it does work, whatever the reason is that it didn’t work before powering everything off. Thank you very, very much. ---
