SOLVED: HDR Content Not Playing

[MaxofGreatness]

Hello again. I got the HVEC content to work by disabling on iGPU drivers, but now I am running into an issue where all HDR content will not play unless I disable tone mapping (which isn't really a long-term solution). It just stop playing and says "Playback Error This client isn't compatible with the media and the server isn't sending a compatible media format". Any help would be appreciated.

Setup:

Windows 10
Intel Core i7-47900
Asrock Intel Arc A380 Low Profile (6GB DDR6)
24GB DDR3 Ram
500GB Samsung Sata SSD (OS)
2x 4TB WD Red Drives (Runs in Raid 1, where media is stored)

Did you make the changes to the Windows Group Policy as outlined in step 3?

Also, what driver version are you running? Intel had some bugs in their driver that broke tone mapping. Reverting to an older driver was a workaround until Intel fixed their driver. We've documented this, including known working drivers, in the Windows "known issues" section.

Been trying this. The driver that used to work is no longer available on the website or anywhere that I could find it. Do you know anywhere else I can download it from?

Looks like 3rd party sites are your only option until Intel gets their Windows drivers in order.

That's why I mentioned in the previous thread to wipe the old driver.
The legacy OpenCL loader used by 4th Gen iGPU may block newer drivers, apparently Intel has not tested their new dGPU on these legacy platforms.

Here are the recommended steps:
1) Disable iGPU in BIOS.
2) Use DDU to erase all display drivers (there should be two at least).
3) Temporarily install 31.0.101.5085 driver until Intel pushes a new driver to fix an issue known to affect HDR transcoding. (We should be there soon)

I got it working. You don't need to disable the iGPU in bios as long as you disable it in the device manager. DDU is essential for it to work, and then I used a link from Techspot to get the old drivers. If someone does this in the future, make sure the version is right by customizing the install in the installer and looking at the version number.

It is also best to turn off automatic driver updates. Otherwise, the driver containing regression may be installed in the background.
