Thank you for contacting Intel® technical support. I will be more than happy to help you.
I understand that you are having issues with the sound on an Intel® NUC Kit NUC7i3BNK.
To better assist you with your request, I will need to check some more information. Please let me know what is the name of the software that you are using to test the audio and to confirm that the audio is broken from and above 88.2/16, and let me know how is the issue happening so we can try to replicate it in our labs. Also, if possible upload a file with this issue to a file sharing service so I can download it and use in my lab test.
Thank you very much for the information. We will perform a laboratory test to try to replicate the issue so we can look for a solution for you.
This may take some time, so I will be contacting you back in a week or less to inform you about our results.
Thank you for your patience. We were unable to replicate the issue with the latest driver version, which was recently released on November 7.
I would recommend you to manually clean install the latest driver and test again to see if the issue was fixed with the update. First, you will need to uninstall and delete the driver in your system, and then you can proceed to manually install the latest driver,
Please follow the steps below to uninstall the graphics driver:
- On the keyboard, press WinLogo key + R, then type in devmgmt.msc
- Expand the Display Adapters section.
- Find the Intel® Graphics Driver. The driver can also be called the Intel® Graphics Media Accelerator Driver (Intel® GMA Driver).
- Right-click the Intel Graphics Driver and select Uninstall.
- Select the check box Delete the driver software for this device.
- Reboot the computer after the uninstall process has finished.
- Download the graphics driver ZIP file: https://downloadmirror.intel.com/27266/a08/win64_15600.4849.zip
- Unzip the file to a designated location or folder.
- Right-click Windows Start icon and open Device Manager.
- Click Yes when prompted for permission from User Account Control.
- Expand the Display adapters section.
- Right-click the Intel® graphics entry and select Update Driver Software.
- Click "Browse my computer for driver software".
- Click "Let me pick from a list of device drivers on my computer".
- Click "Have Disk".
- Click "Browse".
- Access the designated location or folder, and access a folder called "Graphics".
- Select the file called "igdlh64" or "igdlh".
- Click Open, then click OK, and finally click Next. Drivers are now being installed.
- Reboot your computer.
Thanks for your reply Xavier. I did the following updates.
1) I bought a new HDMI cable marked 2.0 on cover. Although my other cables should be 2.0.
2) BIOS was updated from 52 to 54. It didn't helped.
3) HDMI firmware was updated from 1.66 to 1.72. It did't helped.
4 I followed your guide is in previous post step by step. It didn't helped.
So the root-cause can be due to
1. Intel audio driver (HDMI2.0 compatibility)
2. Intel HDMI hardware or firmware (I am afraid that the device itself is wrong but proving it to dealer will be a bit difficult.)
3. Pioneer receiver HDMI input. (Unfortunately I have only the NUC as HDMI 2.0 source but driving amplifier from any other 1.4 compatible device it sounds good.)

Provide a detailed description of the issue
PCM sound from and above 88.2/24 is broken more and more as quality is higher and higher.
Problem exists with Direct Sound and WASAPI too. With foobar2k or Jriver or Kodi or any other player.

How to repro
Please provide steps to replicate the issue. These steps are very crucial to finding the root cause and fix.
A screenshot to illustrate the issue is a huge plus. A video of the failure is even better! Attach to the post or provide the YouTube link.
- Connect HDMI output to 1 of 3 HDMI 2.0 of Pioneer Receiver SC-LX 59
- Change sound format to 2 channel 176/24 in advanced tab of sound settings
- Play something with any player via direct sound system which is usually the default setting.
- Listen whether sound is broken or continuous

Hoping in solution.
Thank you for the information. We will be escalating the issue to the next level of support to be able to look for a solution for you.
Please have in mind that it may take some time to get a result, but we will post back to keep you updated.
The Intel® NUC Board NUC7i3BNB supports for the following formats:
When you have your NUC connected to Pioneer Receiver SC-LX 59 and you play anything on 2 channels at 176.4Khz is when you get the audio broken? How broken?
Is it possible that you test the same but connected to the TV or to any other speaker set? I just want to rule out the receiver.
Thanks for your answer. You can find examples how it sounds, what I mean by broken sound. Sorry if I use wrong expression.
Breafly. This Pioneer receiver has several HDMI input channel but only 3 are HDMI 2.0 (and HDCP 2.2) compatible. I experience broken sound if I connect NUC to any of these 3 HDMI 2.0 port. If I connect to any other 1.4 compatible port, sound is perfect.
Unfortunately currently I have only these two HDMI 2.0 capable devices ergo I cannot try NUC with other HDMI 2.0 device. Also my TV set is HDMI 1.4 or 1.3 compatible. I know that in this way I cannot decide which device (NUC or Pioneer) has problem but any other 1.4 device I have (PCs, laptops) sound perfectly connecting to any port of Pioneer even with 192/24 stream.
BTW something is very strange. You copied part of specification here and max LPCM resolution defined as 176/24. Well when I bought this piece the following was written documentation.
It makes me think. If 176/24 is written there in that time I am not sure I would have bought it at all. May be. Anyway.
I hope you find the root-cause.
Meanwile I tried a laptop with CPU 8250U.
Acer Swift 3 SF315-51-59Y3
Video card is same 620. I don't know whether it is good news or bad news but it sounded perfecty in any way In any hdmi input of Pioneer receiver. Also the fresh spec of Acer does not contains 192/24 mode either. So something is not OK around 620. Or?
