Also … 22.04.2 LTS is mainstream for most.
https://wiki.ubuntu.com/Releases
22.04.3 LTS will be out shortly but until formal release – it’s just “beta”
( My understanding is that we will get the 6.2 Linux kernel … but my info might also be dated )
Does it matter if we’re using Apollo Lake CPUs and need to rely on the v5.15 kernel? Will newer versions of Plex gain anything by running on a newer version of Ubuntu with the older hardware and kernel?
No it doesn’t matter.
You’re fine with 5.15 kernel for all CPUs prior to AlderLake
The new kernel is required for AlderLake, RaptorLake and those which follow because of the P (performance) and E (efficiency) core architecture of the chip

Thank you! I had to use that old workaround (VaapiDriver=“i965”) sometime in the past to fix HW transcoding on my Pentium Silver j5005 NUC. I removed that entry and now HW transcoding is working again.
I’m having the same problem, I only noticed it for the last few weeks so I’m not sure when it started! It worked fine for a few years and not changed any settings. Runs on unRAID in docker, Plex Media Server Version 1.32.6.7468
I tried going back to plexinc/pms-docker:1.32.1.6999-91e1e2e2c as a previous post suggested but that made no difference!
Logs attached, look at around 21:04
Thanks

Based on what I see here, which you confirmed by testing build 6999
- PMS sees the hardware and is trying to download the drivers again (which have not changed — concerning)

Suggest:
-
Check the drivers are indeed downloaded fully. Delete and let PMS get them again if uncertain
-
GID access to the hardware is required (UID is always root at the OS level). Confirm GID assigned is a member of the group which owns /dev/dri/*
Question:
Is this TV/DVR ? If so, I cannot advise further.
Recommend confirming with regular transcode playback of existing file.
Thanks @ChuckPa and sorry its taken a while to get back to you! Over the last couple of weeks I’ve noticed that some files do use QSV to transcode, so after experimenting I’ve worked out that it only has an issue with 4K HDR files! And they work ok if you switch off the tone mapping? So that seems to be the issue!
CORRECT! 
We withdrew 1.32.6 and 1.32.7 because of the QSV problem.
Nvidia is not impacted.
We are iterating down through the pieces which make QSV HDR tone mapping work and are just about there (where the problem appears to be).
At this point, we know what it isn’t and there’s not must left to double check.
For now, 1.32.5.7349 is viable for you to use (on the downloads page)
You can join us here.
This is where we’ll bring the Forum Preview of packages which restore functionality.
Ah ok, thanks for that! I’ll monitor that thread!
