Thank you for reaching the Intel Communities. I understand you would like to get the audio and HDR working as desired, and we can certainly check on this looking for a possible solution or source of the problem.
I would like to get some data from the system to have a better overview of the scenario you have now.
Please provide the following information:
- What is the configuration you have? is the system connected to an AVR or directly to the TV?
- What types of cables are being used? (HDMI, DisplayPort, other)
- Are you using any sort of adapters? If so, what are the brand and model?
- Do you happen to remember the versions of the drivers tested so far?
- Attach the Intel(R) SSU report to your answer
Also, would you please further elaborate on the issue related to HDR? What is the system's behavior?
What is the problem faced with audio? Is it missing, does it have latency issues?
How to get the Intel(R) SSU report?
- Download the tool: http://intel.ly/2pQj9Kk
- Scan the system
- Save the report
- Attach it to your answer
will upload the ssu report soon as i can but remaining info request
set up is Nu7I7BNK to arcam avr 550 to panasonic DX902b
HDMi cables throughout and no adapters
drivers i can list from info gained at work
windows is currently redstone 3, installed in hopes might see improvement but the same as having RS2 installed
126.96.36.19964, HDR works and so does Audio
188.8.131.5278 HDR works and so does Audio
15.46.02.4729 HDR works Audio does not
184.108.40.20649 HDR works Audio does not
15.46.05.4771 HDR works Audio does not
220.127.116.1171_BN HDR works Audio does not
15.47.02.4815 HDR works Audio does not
the problem i am facing is using any driver other than a WDDM 2.1 version i get no audio at all when trying to watch 4k movies through powerdvd 17 when full screen HDR mode is enabled, it also does not switch to 24P mode but that i suspect is down to powerdvd
it will also not play audio with any driver if powerdvd has to change the refresh rate from 24p to 60p from testing in hopes that it would stay 24P
Thank you for reporting back with the information, it is really useful!
I do want to check the SSU report from your system so I will keep this thread handy to get that report.
If additional questions are present, feel free to add them to your answer.
This is a known issue that is been worked out Intel and CyberLink*.
I don’t have any estimated time as of when there is going to be communication about this issue so I will recommend that you keep an eye on this forum for any future updates.
