Failures of Intel(R) Display Audio on NUC

I'm having a terrible time with HDMI on my new NUC. Hours of searching and research have revealed others having similar issues, but those threads always seem to end without resolution. Frustrating.

I have the NUC7i5BNK J31144-309 HDMI port connected to an HDMI 2.0 port on a new LG43UD79 4K monitor 3840x2160 30Hz, Win10 display scaling either 100% or 150%. The NUC BIOS is updated to latest BNKBL357.86A.0063.2018.0413.1542, and I have tried setting the BIOS default display to either AUTO or HDMI. I have simultaneously removed both drivers, rebooted, and let Win10 re-install them. They are the latest available (April 6) versions including Intel(R) Iris(R) Plus Graphics 640 version 24.20.100.6025 and Intel(R) Display Audio version 10.25.0.5.

My NUC is set never to sleep. Whenever the monitor is blanked and turned off, or if the input source on the monitor is switched to another computer, there is no audio when the monitor is restored. The volume control system icon reliably has a red 'x' on it, and there is no corresponding playback device. Going to the Device Manager for Intel(R) Display Audio and using Disable followed by Enable sometimes resolves the issue. Other times, a reboot is required.

This is evidently a long term problem that has not been addressed by Intel but should be easy to reproduce. I also have the problem of all windows getting shrunk to the upper left all the time, but the audio problem is pretty much a show stopper for trying to replace my 8-year-old old Win10 tower with a NUC. System Support Utility output is attached. I could really use some suggestions for things I haven't tried yet.

Thanks,

Curt

Hello

 

 

Thank you for joining the community.

 

 

I am noticing that you have installed Windows® 10 1803 on your system, does the problem happen if the system is running with Windows® 10 1703? Have you tried that configuration on your system?

 

 

Regards,

 

Leonardo C.

Hi Leonardo,

I installed Windows 10 new from disc. It automatically updated to 1803 before I was aware of these problems, so I have no results for 1703. However, I have an 8 year old HP computer connected to the same monitor that also updated to 1803 and it has no audio problem, nor do windows shrink to the upper left. That system has a Radeon 5770 graphics card 3840x2160 30Hz over DisplayPort and uses the AMD Display Audio driver.

Since the audio can usually be fixed by disabling and enabling the device, I obtained Microsoft's devcon.exe utility and wrote this script to be run as Administrator every time I sit down at the computer or switch monitors:

@echo off

set DEVCON=C:\Windows\devcon.exe

%DEVCON% disable "INTELAUDIO\FUNC_01&VEN_8086&DEV_280B&SUBSYS_80860101"

timeout /t 3 /nobreak >nul

%DEVCON% enable "INTELAUDIO\FUNC_01&VEN_8086&DEV_280B&SUBSYS_80860101"

Please let me know if there is any useful information I can collect, or experiments that I can run on the existing O/S to help solve this problem (Intel support ticket 03425388). I believe the AMD driver mentioned above was fixed only recently, so there may have been a recent change to Windows that necessitates that Display Audio drivers be updated.

Thanks,

Curt

Hello csmcd5

 

 

Thank you for your response.

 

 

Could you provide me with the graphics report? One with the display connected to the NUC and the other report with the display connected to the HP system.

 

 

Please follow the instructions below:

 

  1. Right-click on the Desktop, and click on Graphics Properties.
  2. Click Options and Support, and then click Information Center.
  3. Click on Save (save it to your desktop).
  4. Please attach the report to the thread.

 

Could you try to use headphones plug into the display's audio jack to test if when the NUC come out of sleep mode you have any audio output on the headphones?

 

 

Have you also tried to replicate the situation with other display if possible?

 

 

Regards,

 

Leonardo C.

I have the same issue. I have the intel nuc8i7HNK and a LG34UC88-B curved monitor. I plug the HDMI into the NUC and I should be able to see "LG ULTR WIDE Intel (R) Display Audio default device" but I do not see this.

At this time no sound is playing through my LG monitor.

This script does not work for me.

I dont see a devcon.exe in my c:\windows directory

bigbear: devcon.exe does not come with Windows by default (it should because it's a tiny standalone utility). I probably can't send it to anyone directly because it's copyrighted material, but you can Google some contorted procedures for getting it. Microsoft's official procedure requires installing a boatload of development software and it doesn't work, so don't do that -- instead, extract it manually from a .cab file.

Hi,

I have the same problem here, since Windows 18.03 update....

Hi Leonardo,

Please find the info you requested for Graphics Properties at http://fishlet.com/compare-hp-nuc.tar http://fishlet.com/compare-hp-nuc.tar. I recorded images for the NUC and for the HP.

Also note that the HP does not shrink and relocate all the windows to the upper left like the NUC does. Windows remain where they were the previous time the monitor was connected. The NUC makes it painful because I typically have many windows open.

Regarding the audio jack on the NUC, it works properly. It appears as an audio output device whenever the headphone is plugged in. The behavior of the Display Audio is not affected in any way when the headphones are plugged in vs. when they are not plugged in. The Display Audio device is absent after turning on or switching the monitor, whether or not the Realtek device is present. The red X shows on the speaker icon when neither are present.

Regards,

Curt

Hello all

 

 

Thank you for your response,

 

 

csmcd5 could you provide me with the .txt graphics report file when the display is connected to the NUC?

 

 

Steps to get the graphics report:

 

1. Right-click on the Desktop, and click on Graphics Properties.

 

2. Click Options and Support, and then click Information Center.

 

3. Click on Save (save it to your desktop).

 

4. Attach the .txt file to the thread.

 

 

fortify98 in order to assist you better with the specific problem, you are having in your Intel® NUC system. I recommend creating a new thread. Please make sure you add all of the details of your computer so we can get more information about the problem.

 

 

Regards,

I have the same issue where Intel Display Audio stops working when the monitor is Idle and then wakes again. My connection is through the USB-C to DP and this is a new problem since WIndows 10 1803. Disabling/Enabling the Intel(R) Display Audio device in the Device Manager is the only way to resolve this.

Hi Leonardo,

Below is the graphics support information you requested (I don't see a way to attach a file in this forum).

The information does not vary depending on whether the device is in the working state or not. The information is not available for the working HP system, as there is no Intel desktop context menu in that Radeon-based system.

Regards,

Curt

Hello all,

 

 

Thank you for waiting,

 

 

I was working on the scenario that you have with an Intel® NUC7i5BNK with the BIOS 0063, Intel(R) Iris(R) Plus Graphics 640 driver 6025 and Windows® 10 64 Build 17134 connected by HDMI® to a LG* display (first test) and a Samsung display (second test), the NUC has been set up never to go to sleep mode and set the display to sleep in 2 minutes, after the display goes to sleep and come up again I have a "X" on the audio icon for about two seconds and after that everything starts working normally again.

 

 

Regards,

 

Leonardo C.

I don't have this problem anymore, maybe a WIndows Update fixed it.

hi Leonardo,

I have an Intel NUC7i5BNK with BIOS 0065, Intel Graphics driver 6025, Windows 10 64 build 17134 connected by DisplayPort to an Iiyama PROLITE XUB3490WQSU-B1 (only display) and I still have the issue that when my monitor wakes from sleep the Intel Display Audio is no longer working. Only a restart (or disabling/enabling Display Audio component in Device Manager) brings it back.

Hello ferjan

 

 

Thank you for your response.

 

 

Could you provide with the type of video connection, is it USB-C to Display port or HDMI® to Display port? If it is possible please provide me with the model number of the video connection that is being used.

 

 

Regards,

 

Leonardo C.

USB-C to DisplayPort... I don't think I had this issue prior to Windows 10 1803, but no way to verify that anymore.
