Brand new TV, just a day old. When playing a show in 4k it will play 1-2 minutes then it will buffer until I get a message stated that there was an issue with playback. I enabled always connect to insecure network and preferred, tried deleting the app and installing it again, nothing works.
If anyone can please help me I would truly appreciate it.

A strong 5 GHz Wi-Fi connection is preferred over wired Ethernet. The TV’s Ethernet port is most likely 100 Mbps. Many 4K HDR movies burst above 100 Mbps. A 5 GHz Wi-Fi connection will be faster than the wired Ethernet.
Choose the AC3 audio stream instead of TrueHD.
The TV does not support TrueHD audio. Therefore, it will be transcoded by Plex Media Server. Choosing the AC3 audio track should allow Plex to direct play, instead of direct stream, the movie.
Update to the 64-bit version of Plex Media Server
The system is running the 32-bit version of PMS. Plex now ships a 64-bit version.
Nov 26, 2023 15:46:43.175 [23592] INFO - Plex Media Server v1.32.7.7621-871adbd44 - Microsoft PC x64 - build: windows-x86 windows - GMT -05:00

The “update available” button in Settings → General does not offer to update to the 64-bit version. You’ll need to download the 64-bit version from plex.tv. You do not have to uninstall the 32-bit version. The 64-bit installer will take care of that. This affects only the Plex Media Server program. The Plex Data Folder and your media files are not touched during the update. After installing the 64-bit version, future updates will also be 64-bit.
The 64-bit version has a more efficient video transcoder. It does not need to move as much data between the system RAM and GPU RAM when transcoding video (zero-copy transcoding).
The 64-bit version is also required to take advantage of hardware acceleration when transcoding and tone mapping of 4K HDR media. See HDR to SDR Tone Mapping.
I tried all the above, but still getting the same issue. I do have a 5GHz router and the speed is more than enough and updated to the 64-bit media server Screenshot 2023-11-28 101938.zip (2.2 MB)

As for the AC3 audio stream, I don’t see that option within the Plex Samsung App.
Uploaded some images. Server Error Crashes at the same time every time for the 4K videos. Time dependent based on the movie that’s being streamed.
You can change audio tracks on the film’s library page by selecting the 3 dots and then ‘select audio track’.
re: the file in question.
The video is 4K HDR10 so will direct play fine.
The 1st audio track is TrueHD - this will result in a transcode to AAC.
The 2nd audio track is AC3 - although this would usually direct play, the Plex Samsung app forces a transcode to AAC as it doesn’t like anything that isn’t the 1st audio track. Even if the 2nd audio track is AAC, it’ll still switch to Direct Stream.
PGS subs are Direct Play supported as of some point in the past year.
So basically, without remuxing the file you’ll be transcoding the audio.
I tested the exact same file on my 2022 Samsung QN95B - though for now I’ve only tested a 2GB / 10min chunk that I cut using MKVtoolnix - and with the subtitles enabled the playback crashes and burns after around 3mins 30secs in the way you describe.
Disable the subs and it seems fine (though I’ve not let it play for more than 6-7mins).
The only setting of yours that doesn’t match mine is I have the ‘normalize multi-channel audio’ setting disabled (no tick). I think that’s all done on the player side though so I don’t know how much of a difference it makes.
