My connection to PMS keeps dropping every 18 minutes or so when playing back a 1080p with TrueHD 7.1 audio that is transcoded to Flac. This happens on both iOS and Apple TV, and when it does it takes a minute or so before I can log in to PMS via web.
I can’t manage to tell what is going on when looking through the log files.
I see you have an AlderLake CPU
PMS sees the GPU (Alder Lake-N [UHD Graphics]
When it goes to playback, the hardware can’t be found.

I see where you did a SEEK on the iPhone and it terminated playback.
Can you get playback on other devices ?
Yes, I can playback on iPhone, Apple TV, and web, but PMS crashes if playing back on iPhone and on Apple TV after about 18-20 minutes.
The GPU wouldn’t be leveraged for audio transcoding, right? The video is not being transcoded.
If you’re doing audio – correct, the GPU won’t be used.
My bigger concern is that the GPU can’t be found properly.
It saw it at startup but the scan afterwards didn’t find it.
would you consider stopping Plex,
in the terminal, go into the Plex Media Server/Codecs directory,
and remove everything except the .device_id file ?
Next, go into the “Drivers” directory and remove everything there.
After doing so, restart PMS. It will download both fresh drivers and codecs.
