Plex app version on Shield?
https://app.plex.tv/desktop#!/settings/devices/android
Make sure you have current version of Plex app on the Shield. The version that ships on the unit is most likely out of date. Current Version is 7.12.0.
Nvidia Shield settings:
Display & Sound -> Advanced Settings -> Surround Sound = Auto.
Plex App on Nvidia Shield settings:
Advanced -> Passthrough = HDMI
Video -> Display Information = On
Video Quality -> Adjust Automatically = Off
The YAS-107 Owners Manual (HDMI signal, Audio signal, pg 41) says it supports bitstreaming Dolby Digital and dts audio. It is unclear if this includes Dolby Digital Plus (EAC3) and dts-HD (dts 7.1 is dts-HD), as they are not specifically listed as included or excluded.
During playback on the Shield, pull up on-screen controls (tap bottom of ring on remote, pause video, etc). Information Overlay will appear in upper left corner.
What does it show when playing media with the various codecs - AC3/EAC3/dts/dts-HD?
If transcoding, either audio or video, what reason is shown?
How does what is shown on-screen align with what is shown by the soundbar’s Decoder Indicator (Green = Dolby Digital; Red = dts; Off = PCM)?
