NUC8i5BEH Realtek Audio Drivers and Win 10 1903. I'm attempting to get the audio to play through the HDMI to the Asus Monitor.

Jump to solution

I've run the AUD_Win10_RS4_6.0.1.8596 driver package after it removes the old driver which happens to be the same driver it works still it started to reinstall it. If I boot to a drive that has Win10 1809 the audio works fine. It's just when I use the 1903 image that I have this problem.

Hi @RHout​,

 

Comparing the IDSA Reports shows that the Intel® Display Audio was missing.

These Driver is essential when using HDMI Audio.

 

Happy to hear that your issue is solved now.

The Intel Graphics Driver controls in addition to the video output the audio HDMI output either. The latest Graphics Driver for your NUC you may download here: https://downloadcenter.intel.com/download/28888/Intel-Graphics-Windows-10-DCH-Drivers?product=80939 (download the igfx_win10_100.6912.exe). The Realtek Audio Driver controls audio output trough the audio jack only.

 

My advice is to take care that the following firmware/software will be updated:

Bios ver 0073 https://downloadcenter.intel.com/download/28951/BIOS-Update-BECFL357-86A-?product=126148

Intel Management Engine Driver https://downloadcenter.intel.com/download/28215/Intel-Management-Engine-Consumer-Driver-for-Windows-...

Chipset Driver https://downloadcenter.intel.com/download/27998/Intel-Chipset-Device-Software-for-NUC8i7BE-NUC8i5BE-...

Hi @LWAKSMAN​ 

I'm using the Intel Driver Support Assistant and it says all is up to date.

I also confirmed all firmware/software is at the level you recommended but I'm still unable to get audio from the HDMI.

It's got to be a problem with 1903 but how to convince Microsoft of that.

Thanks for the input.

I am running Windows 1903 on my NUC8i5BEH with

 

BIOS 0073,

Intel HD Graphics Driver 26.20.100.6912,

Intel Display Audio 10.27.0.4,

Realtak Audio Driver 6.0.1.8569 (which shoudn´t be relevant here),

 

using HDMI Audio without any problems. But I am using a Samsung U28E590DS/EU.

 

Can you attach a detailed System Report from IDSA?

Using these BIOS-Settings Audio via HDMI works fine for me ...

Hi @Trial-Member​ 

I've been able to get it working since I posted this but what's still driving me crazy is I don't know exactly the root cause. It comes down to the Intel Display Audio driver not being installed. But what I don't understand is when I took the system image it was working and all drivers were the same. The only difference is I ran the AUD_Win10_RS4_6.0.1.8569 and it uninstalls something (it says the Realtek driver but more on that in a sec) then reboots and the audio works. I cancel the remainder of the setup and everything works great. And I still have the Realtek Audio driver installed. So when it uninstalled something I don't know what it's actually removing.

Thanks for the BIOS Tip also, I had verified that was checked.

Attached are 2 of the IDSA reports if interested one is from the Image that doesn't work and the other is from the image that is working.

Thanks again for all your input.

I noticed that also but I don't know how to get and install that specific Intel Display Audio driver. When IDSA scanned the system it said it was up to date. And all I did to get this working was run a Realtek High Definition Audio Driver installer and stop it after the first reboot. It's almost like the Realtek driver prevents the system from detecting the Intel Display Audio output.

Thanks again for all your feedback on this.

Hello @RHout​ If you will do what I've advised you six days ago, your audio was working already (i.e. download and manually install the latest Intel Graphics Driver).

Edit:

In order to be able to install the latest Graphics Driver, you need manually uninstall the currently installed driver first (you will see Microsoft Basic Graphic Driver in Device Manager).
