Thank you for joining the Intel Community Support.
I understand that the audio setting 24bit/192khz is not available in Windows after installing the latest graphics driver available. To address this issue properly, I would like to gather basic information about your system and setup.
First, please scan your system using the Intel® System Support Utility. Follow the steps below:
1.Download the Intel® System Support Utility and save the application to your system.
2.Open the application and click Scan to see system and device information. The Intel® System Support Utility defaults to the Summary View on the output screen following the scan. Click the menu where it says summary to change to Detailed View.
3.To save your scan, click Next and click Save. You can save the file to any accessible location on your computer.
4. Attach the report to this thread.
Also, please provide the following information:
3.Describe the connection configuration. For example, the Intel® NUC is connected to the HDMI input of the receiver; the receiver is connected to...
4.Please explain the steps you follow so that we can reproduce the issue, if possible.
Thanks for giving Advice.
Ok, connection of my Stuff is:
Nuc > HDMI > Pioneer SC-2024 > HDMI > Panasonic TX-58DXW784
As i had written before, there were no Problems with this Combination and using the Audio-Driver Ver.6.16
from the Graphics-Driver Package GFX_WIN10_64_188.8.131.5264.
I had to install the 6.16 version manually after installing the Graphic-Driver, but that´s ok, i can live with it.
But now after trying the newest Driver, no possibility to go back to the 6.16 version. Thats maybe a Windows 10 Problem, i don´t know yet.
Changing to 16bit/192khz is possible in the Windows- Audiosettings, but there is no 24bit/192khz Option in the List !
And i have a lot of 24bit Audio-files that i can´t play anymore.
When it all was running as mentioned, the Pioneer AVR shows the right Sample-Setting 24bit/192khz on the Display.
I just cant´understand why it was removed from the newer Audio-Drivers when it in the HDMI-Specifications is clearly
defined for HDMI 1.2 max. is 24bit/192khz on 8 Channels and the Nuc-Box has HDMI 2.0a Standard.
And just to say it again: IT IS A DRIVER-PROBLEM, not a Hardware-Problem !!!
The Nuc can do it, the Pioneer AVR can do it.
Thanks for your Time

Thank you for the information provided.
I was checking the information carefully and I was wondering if you tried installing the latest version available for the Intel® NUC or the graphics controller. I would like you to perform a clean install of the latest driver for the Intel® Iris™ Plus Graphics 640.
Please follow these steps:
1. Disconnect your unit from the internet.
2.Please uninstall both the Intel Graphics driver and the Intel Display audio driver. To do this, please follow the steps on the link below under these sections:
-Uninstalling the Intel Graphics Driver via the Device Manager Method
-Uninstalling the Intel® Display Audio Driver or the Intel® HDMI Audio Driver via the Device Manager Method.
3.Restart your Intel® NUC. Please go to the device manager and check if Windows installed another version of the graphics driver. If it does, please remove it and restart your computer one more time. Repeat the process until you get the Microsoft Basic Display Adapter.
4.Once you do, please proceed with the clean install of the latest graphics driver version. Please find the link below:
5.Once the latest driver has been installed, you may enable the internet connection again.
6. Please let me know how it goes.
After trying the uninstal-procedere as mentioned, (yes, there was the MIcrosoft Basic Driver in the Device Manger List) and installing the Driver You posted,
i am sorry to say this,
as said before, no 24bit/192khz in the Microsoft Audio Manager List.
Highest possible Sample-Rate is 24bit/176.4khz.
The funny part is, the Windows Audio Manger recognised that the Pioneer AVR has 24bit/192khz support.
Then i tried again to manually install the older Version of the Audio-Driver 6.16 and guess what ?
It works !!!
So, it is just a fact that the newest Audio-Driver can not do 24bit/192khz !
And no thanks, i am not trying to use any other Driver as it runs yet, finally. (even the next "Newest Version" i am not interested)
But i am really glad that You take some Time for helping me with this matter.
ps: Maybe a short Message to the Intel Driver-Programmer Group should be a good Idea to get rid of this Problem.
I am glad to hear that you were able to install the older driver version, which works better for you. Because your feedback is highly appreciated, I would like to do further research about this issue.
Please fill out the following information. It will be really helpful.
I am just writing to follow up on your case. Were you able to fill out the information provided before?
I look forward to hearing from you.
Sorry for being late with a reply, lot of work at the moment.
I really don´t understand what i should do with this Issue-List You posted since it is almost for Graphic-Issues.
There is no Graphicproblem on my Nuc-Box, it is only the Problem that the older Driver is more compatible for HI-Res
Audio as the newer Versions can do.
It should be helpfull when in the Drivers-Readme not only the Graphic-Fixes or changes are explained,
since there are changes to the Audio-Part as well.
Audio-driver 6.16 : Hi-Res Audio no Problem (Folder-Size 1,96MB)
Audio-driver 10.22 and up : no 24bit/192khz support (Folder-Size 5,87)
so,what are the changes when the newer Version is 3 times bigger and could not support all Audio-Sampleformats
as specified in the HDMI 1.0 and higher ?
By filling out the information I sent you, I will be able to gather additional information to forward this issue to the proper department. Even though there is no graphics issue with your unit, the audio driver is included when you install the driver package.
Probably, there is a regression issue that we can fix, but I need to get the confirmation from the proper department.
Please let me know if you can help us filling out the form so that I can confirm why the Audio-Sampleformat was not supported by the newest driver available. I would like to follow up on this issue, so I will try to get as much information as I can about this.
Thank you for your feedback.

Hello Wanner G.
I tried my best to fill out the Information-List, hope it helps.
If something is missing, please let me know what and i try what i can do.
I appreciate your help.
I will forward this information to the proper department and I will post an update as soon as I have it available.
Wanner G .
This may be difficult to explain but if you check the hardware specification for the product: https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/NUC7i5BN_NUC7i7BN_TechProdSpec.pdf and you go to page: #25, please check the Integrated Audio Provided by the HDMI and Type C interfaces:
If you look at the table above, it means that the hardware has been validated to 176.4Khz/24 bit, 8 channel, of course this has to be supported by driver, it is very common that the hardware has the potential to support additional features (in case sample rates) but validation sets the device to a certain capability.
If a previous driver is not locking up the audio device to the hardware specification and allows a higher sample rate, I would recommend that you stay with it if you are not having any additional issue.
Really funny, the List you had posted.
By simple changing the Tech-Specs it doesnt explain why the 24/192 Samplerate was banned from the new Drivers.
And to make one Point clear,
You Guys tell us the Nuc´s are HDMI-Standard 1.0 and above cappable.
Simple a LIE when looking at the "New" Techspecs !
Look at this and try to explain why i should believe Intel Nuc-Boxes are full HDMI Standard Compatible:
In the Tech-Specs i had downloaded last Year when i buyed the Nuc-Box this is on Page 25:
You are correct, on current TPS: https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/NUC7i5BN_NUC7i7BN_TechProdSpec.pdf page iv, you can find the changes we have done to the documentation.
We changed it from 192Khz/24 bit to 176.4Khz/24 on October 2017.
The TPS also states the following: Intel NUC Board NUC7i5BNB and Intel NUC Board NUC7i7BNB may contain design defects or errors known as errata that may cause the product to deviate from published specifications. Current characterized errata, if any, are documented in Intel NUC Board NUC7i5BNB and Intel NUC Board NUC7i7BNB Specification Update.
I apologize for any inconvenience this may has caused.
