Transcoding TrueHD to AAC

Plex Players Streaming Devices

Server Version#: 1.21.0.3711-b509cc236
Player Version#: 8.10.0.21911
Shield: 8.2.1 (32.8.435.31)
Soundbar: HW-Q90RWWB-1012.6
Cables: HDMI 2.1

I’ve been scratching my head and reading posts with related issues to no avail!

I’m using a Shield (2017) as player directly plugged into my soundbar (HW-Q90R) which is compatible with TrueHD, both are running the latest firmwares.

Yet the audio is transcoded down to AAC (why not AC3? That’s another issue) and playback info gives the reason as being " TrueHD audio is not supported by the device" which is not true.

My setup is as follows:

Nvidia Shield (2017) >----> HW-Q90R >----> LGC9

The Shield’s Status->HDMI->Audio mode shows: PCM 16 bit, DD, DD+, DTS, DTS HD, Dolby TrueHD, DD+ Atmos, TrueHD Atmos. Which by my understanding means it is ready to passthrough all these audio formats to any compatible devices.

Any help much appreciated!

*** SOLVED ***

As it turns out the “pass-through” setting on the Plex app for the Shield is turned off by default. It might very well say that the shield is ready for TrueHD 7.1 in the “audio mode” but that is misleading. Everything is fine now!

Are you saying that within the Plex app itself it wasn’t set to HDMI on pass through? Or were you saying that’s a setting for the shield itself?
