Audio fails when using Dolby TrueHD on Dolby Countdown Clip

Server Version#: 1.18.7.2457
Player Version#: 7.28.0.15501 ba34f115 on Shield TV 2019

I’m running into more issues like this lately and I’m not sure what’s causing them.

I have a Shield TV 2019 running the Plex app. The plex server is on a Ubuntu 16.04 LTS platform. I have downloaded the Dolby Countdown demo clip in lossless format from:

I am also using the Dolby Spheres demo in lossless format from the same site.

When I play the Countdown clip the audio makes an extremely brief fuzz noise and then no sound is heard at all. When I play the spheres clip the audio plays fine for the most part with just a glitch in one part, but then the video freezes in multiple places. When I change both clips to use AC3 5.1 stream instead of TRUEHD 5.1 stream everything works fine. But when I switch back I have the same issues again.

I can play other clips using TRUEHD without any issues. Audio is set to HDMI passthrough in plex and all Dolby formats are supported by my receiver (Denon AVR-X3600H). These clips used to work just fine and now I’m having these issues seemingly with new releases of Plex. If I set the Shield TV to decode Dolby for me the problem goes away, but when I turn off Dolby processing and it passes the stream to the receiver the problem comes back, so it seems to be a problem in the passthrough.

The receiver can decode TrueHD though as it does it on other clips. Any help is appreciated.

I confirm having the same issue with this demo file on my Shield TV pro 2019 (8.1.1 firmware) and the latest Plex client for Android TV
I use a Onkyo TX-NR656 receiver in passthrough mode

The Dolby Sphere V2 lossless Demo is having an issue also bu this time it is the video that is freezing

I’m glad I’m not the only one running into this issue. Is there a way to report this to the developers so they can find a solution?

I am also having issues with the Dolby Spheres freezing midway through the file! Thought it was my new Shield Tube that was having issues!

I have tried switching off auto framerate and auto resolution switching with NO luck. Kodi plug-in on the same device does not have this issue (in passthrough mode also)

Problem still occurs in v8.0.0 of Plex Android TV player

Hi, any news from Plex team on this subject ?

Solved by 8.2 Shield TV firmware upgrade
