I'm trying to figure out what I've done wrong and in all my searching, well there's a bunch of different solutions, of which none have worked for me.

The iGPU that I am trying to pass through to plex for hardware transcoding is the one within the Intel i3 N305.

I have tried the plugins for Intel GPU Top, SR-IOV, GPU statistics. I've tried adding "/dev/dri" to the Plex container for the igpu. I've tried adding "device /dev/dri" as additional resources. I've tried adding xe.conf with xe force_probe=46d9 with and without i915.conf having i915 force_probe=46d9 and with !46d9 instead. With and without the "blacklist i915" line.

The most I've ever seen from the dashboard gpu information was with xe.conf "xe force_probe=46d9" and i915.conf with "i915 force_probe=!46d9". This then shows the widget receiving at least some data as the voltage is fluctuating at 0.1v where as without the xe force probe and with blachlist and then force_probe=46d9 in i915.conf everything is 0.

In all of these different configs, I never see the checkbox for enabling hardware transcoding. Looking at the log for the Plex docker container... there is "Critical: libusb_init failed" but I think that is for trying to connect to the tvtuner and not a high priority as I haven't purchased a plex pass yet. I also don't want to go about buying a plex pass if hardware transcoding isn't going to work. Same goes for Unraid, which is currently in trial status. I came from terra-master's OS which has its own issues, but transcoding was functional there.

In Plex's logs, downloaded from the app's webui, the only thing I'm immediately seeing relating to the gpu is the following:

...which makes me think that Plex is seeing it, maybe??

What can I provide to help determine a solution for this?

Thanks in advance!

Additionally, running "docker exec -i Plex-Media-Server ls -l /dev/dri" from Unraid console returns...

...which is a little odd, but I'd assume that the container is set up in a way that it would see the device.
