Nvidia Shield TV 2019 - Dolby TrueHD not played with Plex native Android TV player

Plex Players Streaming Devices
1

Server Version#: 1.20.4.3517 (Synology DS416play)
Player Version#: 8.9.0.21537 (Nvidia Shield TV 2019)

Audio System : AVR-X1600H (with eARC and full support of Dolby TrueHD / Atmos)
The Shield is directly connected to the audio system.

If I play a TrueHD 7.1 movie, Plex will transcode the movie and I have lags. I I read the same movie with MX Player or VLC, there is no transcode (direct streaming).

I tested with Kodi + Plex add-on and it works like a charm with TrueHD 7.1 with Pass-through enabled.

So, I think TrueHD 7.1 support for Plex Player on Android TV is missing…

Set your Plex Media Server to gather debug, not verbose, logs. See Reporting Issues with Plex Media Server for detailed instructions.

Check the audio settings on the Shield:
Device Preferences -> Display & Sound -> Advanced sound settings -> Available Formats = Auto.
Note: Do not change from Auto. Enabling / disabling specific audio codecs results in all audio transcoding.

Check settings in the Plex app on the Shield:

Video Quality
 Adjust automatically = OFF
 Home Streaming = Maximum
 Remote Streaming = Maximum (if Shield is remote to Plex server)

Advanced
 Passthrough = HDMI
 Network Logging = On
 Enable New Player = On

Play a movie with TrueHD audio with subtitles off.

Is the video and/or audio transcoding?

If still transcoding:

  • Let the movie play for ~30 seconds.
  • Stop playback. Wait 1 minute for logs to catch everything.
  • Pull Plex Media Server logs.
  • Pull Plex app logs from Shield. See Android, Android TV, Fire TV Logs. Note 1: Leave Plex app running, otherwise you cannot access the logs. Note 2: Use http, not https, to connect to the Shield to pull logs (http://<shield_ip_address>:32500/logging).
  • Post logs to the thread.

Hello,
I followed all your instructions:

  • transcoding with Plex native app is still active
  • transcoding with Kodi / Plex add-on is inactive => direct stream

Here, you cand find the logs.

Direct stream with Kodi / Plex

Issue is still present with the latest versions of player and server…
Why Kodi+Plex allow direct stream and not the native player?
It’s very strange…

It seems to be an issue with Dolby formats (and an old issue of what I can read in this forum…)
With DTS (DTS, DTS-HDMA…) no issue, Plex play with direct stream.
