Firecube Dolby TrueHD Passthrough and video stutter/pauses

[xelp]

Hi all.  I have used Jellyfin prior with uncompressed codecs.  In fact it is the very reason I started using it as Plex will not handle those as far as pass through.  And that is also the entire reason I use a Firecube because it too can pass those through.  Most other devices will not except for a shield.

My setup is simply Jellyfin on a Firecube, connected to a Yamaha Receiver, connected to a TV.  Normally works great for 4K HDR + TrueHD sound.  But for some time, when I play a title with TrueHD it plays but I get 1 frame about every 3 seconds.  The sound I think is stuttering with it.  If I swap that same title to say 5.1 it works fine.

This is not being transcoded.  In fact if it is it works fine.  Reason I say that is my Firestick was doing the same thing.  But its just a stereo TV no receiver so it should transcode it but it was not and it had the same stutter.  Soon as I forced a transcode it was ok.

DTS-HD seems to be fine as well, I think its just TrueHD. 

My server is Windows 11
I have tried 10.10.7 and 10.11.x, they behave the same
Plex plays these files fine but its not a comparison its transcoding the sound
I have tried this on several 4K titles

Thank ytou

Am I the only hoser using a Firecube?

I ended up working on this for hours trying all combos of settings. I was fairly convinced it was not Jellyfin and it was the Firecube or my receiver. Tried everything but always the same, with TrueHD and just passthrough Jellyfin video stutters really bad, as in a frame every few seconds. Ironically the sound itself seems to be fine.

In trying to solve this I read Plex now will handle TrueHD passthrough. I tried Plex with no settings change and sure enough it worked fine. So I guess my fix is to watch the 4k TrueHD stuff on Plex unfortunately.
