Nvidia Transcoding Stopped Working

[kylelavery88]

I recently installed a Nvidia 3060 into my Unraid server for transcoding purposes. I use Plex Media Server and was able to successfully select my GPU for transcoding and get it up and running. It worked temporarily and then stopped working. I've tried rebooting, updating the Nvidia driver, updating BIOS and updating Plex. Unraid is also up to date.

 

I also noticed some errors in the system log that may or may not be related:

Oct 30 20:45:09 Tower kernel: ACPI BIOS Error (bug): Failure creating named object [\_SB.PC00.PEG1.PEGP._DSM.USRG], AE_ALREADY_EXISTS (20220331/dsfield-184)
Oct 30 20:45:09 Tower kernel: ACPI Error: AE_ALREADY_EXISTS, CreateBufferField failure (20220331/dswload2-477)
Oct 30 20:45:09 Tower kernel: ACPI Error: Aborting method \_SB.PC00.PEG1.PEGP._DSM due to previous error (AE_ALREADY_EXISTS) (20220331/psparse-529)

 

Needless to say, this has proven to be very frustrating. Can anyone advise on what is going on?

An update for those who may be having the same issues:

 

After much research I discovered that my ACPI errors were being caused by Plex Media Server. After digging into the logs for my Plex container I found audio-related codec errors. The solution for me was to delete Plex's codecs folder. The ACPI errors stopped immediately and transcoding began working again.

 

For those who may find this useful, the folder location is:

appdata\Plex-Media-Server\Library\Application Support\Plex Media Server\Codecs

 

Plex will automatically redownload the necessary codecs when restarting the docker container.
