Server Version#: plex 1.30.2.6563_1.7.27 (Official Chart on TrueNAS Scale)
Player Version#: various. Web, Roku App 7.0 -build 24, and Android TV app v9.15.0.38159
I have tried repeatedly and I cannot get my movie files that have Dolby TrueHD soundtracks to play. I’ve tried just about setting I can find. It doesn’t seem to matter if they are 5.1 or 7.1 tracks. On the Roku apps, the playback spins and shows a % for about 5 seconds, then it comes back and says playback has stopped due to a number of playback errors. Check Connection.
The Android app (on a Hisense SmartTV) just keeps spinning with no % showing and no errors. It continues for at least several minutes before I stop.
On a web interface (Firefox), it spins for a few seconds and the gives an error that says “Playback Error: Conversion Failed: A required codec could not be found or failed to install.”
This a TrueNAS Scale Build (22.12.0) using the official TrueNAS Chart with no advanced settings modified. Other than the TrueHD movies, everything else plays back brilliantly on all devices/apps. I have noticed that the TrueHD movies will play back perfectly with Direct Play on using either the Windows Plex Desktop or Linux Desktop app. These same files play back perfectly using Kodi and my SMB Share. It is only a problem with Plex via the Web, Roku and Android TV apps. I don’t typically use on mobile devices.
As far as the source material, it is almost all in .mkv format (encoded with either h.264 or h.265 and it doesn’t seem to matter which encode). Most only have one soundtrack that was kept, I usually kept the best quality either AC3, DTS, DTSHD-MA, Multichannel PCM, or TrueHD. None of the movies are 4K. They are all 1080p rips from standard BluRay discs in my collection.
Prior to this TrueNAS Scale server build, I was successfully running Plex Media Server inside of an LXC within a Proxmox VE server and I did not have any issues playing back these files to the same Roku devices, in the same network, etc. I mean it was working correctly on the other server a week ago.
This server is not resource limited either. It is a Xeon E5-2680v4/64GB ECC RAM running SSDs for apps and a large ZFS pool for storage.
Any help would be appreciated. I’ve never had to create Plex Log files, so if that can help, let me know the best way to collect them. The log from the TrueNAS app seemed to be very limited? Only a few startup lines and then the libusb_init failed error, which I understand doesn’t really apply.
