Just to confirm …
transcoding WORKS - plexmediaserver-1.42.2.10156-f737b826c.x86_64.rpm - Unknown NVIDIA (2f04) reported
transcoding FAILS - plexmediaserver-1.43.0.10162-b67a664b6.x86_64.rpm - Unknown NVIDIA (2f04) reported
Looking at the logs it appears to be failing with the audio decoder…

Anyhow, I know you guys hate log snippets but I’m not putting my full logs up here so please DM me if you need them. For now reverting back to 1.42.2.10156.
BTW… here is a snippet from when it works with 1.42.2.10156 and you can see Unknown NVIDIA (2f04) is detected but is used correctly.
