TRUEHD 7.1 Problem. Other formats are OK

Plex Media Server NAS & Devices

Hello,

i have a home cinema Samsung HT-D5500 and a NVIDIA Shield TV 2017.

Direct Play : AC3 5.1, DTS 7.1 and 5.1, DTS-HD 5.1, DTS-HD MA (5.1 and 7.1) : OK
But not TRUEHD 7.1 : not ok

All settings (NVIDIA+Plex) are “enabled” for Passthoung and “Always” for Surround Sound. Play with Original Quality.

Do you have a idea ?

Thanks for your help

Denis

Same here… everything works… Even DTS:X…

But when i want to play a movie with TrueHD or Atmos, The Plex app crashes or i get the message: Server is not strong enough to play this Movie.

Its very frustrating…

it works.
that’s what I did:
I disabled HDMI CEC
updated shield + plex (automatic)
usb audio mode to 5.1 surround and reboot ! (very important)
after reboot, passthoungh to auto
Plex> advanced> direct forced play
live stream> disabled
passthough> auto or enabled (something like that)

I hope it works for you too.

All formats are OK

Force Directplay seems to be removed from settings…
I now have problems playing 4K movies stored on my super PC. (i7 7700K with 16 gb ram and so on)
It was a week ago or so, that this was not a problem. But it might be something with the new Nvidia 6.3 update that messed up Plex app?

I know I am necro this thread but I too am having these issues on all of my devices, (chrome cast (both 4k and 1st gen), PC’s (4 different ones with different specs) (web client), android app (multiple devices), and nvidia shield (2017). If anyone has found a solution to this that would be a great help thank you.

It is only True HD causing the issue.

I’m experiencing a different TrueHD 7.1 issue where Plex thinks it needs to re-transcode my 4k movies to 4k. My CPU can’t keep up with that and buffers every 3 seconds.

If I switch the Audio track to the AC3 5.1 (director commentary) and then back to TrueHD 7.1, the issue goes away and everything plays gloriously in 4k with HDR.

I’m streaming to a Samsung TV, but maybe this workaround will help you too?

Best of luck!

Oh jea Baby!!! This way is working for me.
Direct stream 4K (HEVC Main 10 HDR ) and Dolby Atmos sound without transcoding anything after switching from TrueHD to 5.1 and then back to TrueHD

if you are having problems with TrueHD and/or ATMOS streaming to your TV, its most likely because the TV does not support the HD audio directly.

For example with an nvidia shield, you would need:

shield > truehd/atmos receiver > 4k tv

this Plex, 4k, transcoding, and you - aka the rules of 4k - a FAQ may or may not help.
