NUC8i5BEH here, with WIndows 10
I have an unknown device in the device manager with the following id:
I have installed all drivers from intel support and the only difficulty I had was with the realtek audio drivers. Normally, it would not install. It would complain for unsigned driver and then fail with error code 0xE0000100. I used then "run as administrator" and it did finish.
The file I used was audio_win10_64_220.127.116.1169
Still, the unknown device remains there.
Anyone else encountered this?
No, I have not resolved this.
I used the latest driver package in the same way.
Device manager finds something to install for the unknown device, but it will not install.
Still, I do have sound at least.
The "Detection Verification" device is related to Intel Smart Sound Technology, and the supporting driver is part of the Smart Sound Technology driver package, and not the Realtek audio driver, so no amount of Realtek audio driver installation is going to resolve a yellow bang error (missing driver) for this device.
I have also seen a yellow bang appear for this device in my NUC8i7BEH. I believe it is caused by Windows Update not download and installing all parts of the Intel Smart Sound Technology driver into the system.
A remedy is to manually download the Intel Smart Sound Technology driver package from Intel website and install it.
I think you are correct.
that seems to be relevant, although it is for the previous generations of nucs.
I have not found a different Intel Smart Sound Technology driver package from Intel apart from what is in the IntelHDASST directory together with the realtek drivers.
maybe it's a buggy driver and/or maybe windows updates are to blame.
for the moment I leave it as is and wait for the next version.
