I tried to open the report but the system is giving me an unknown error. Could you please send me the results of our Intel® System Support Utility.

Let me know how you are getting the Audio (through TV (HDMI), speakers through Audio jack or any other.
Thank you for your update. Your system is working with older drivers and BIOS version. Also, I noted your RAM is running at 2666MHz, your processor supports DDR4 2133MHz memories, higher speeds will damage it.
I suggest you the following; get into the BIOS and change memory speed to 2133MHz at 1.2V; update motherboard drivers (start with chipset driver) and finally update the graphics driver from Intel website.
If problem continues continue with the BIOS update. There are 8 new BIOS versions.
Asus Z170M-Plus Driver & Tools
Intel® Graphics Driver for Windows® 10 v 18.104.22.16863
Thank you for your update. I noted you updated the BIOS and graphics driver.
Could you please let me know if you updated the Chipset, Management Engine and Audio drivers? Send me your system configuration, I mean the brand name of the monitor, type of video cable, include any adapter, speakers and any other device related to Video and Audio.
The monitor is Dell S2216H with integrated speakers and stock hdmi cable. It had a generic Microsoft pnp driver. But I've installed a specific one from Dell just now.
Realtek Driver was 22.214.171.12496. I updated to 126.96.36.19936 just now.
I believe I installed the latest Management Engine drivers, yes. 5 screenshots attached.
Thank you for your update.
Let’s try this workaround. Reinstall the monitor driver again; use the link below:
Dell S2216H 21.5 Monitor with LED Driver
If you get the same issue after idle again; right click the Audio icon (right lower corner), select Playback devices and check if you can see the speakers of the monitor. (try to set them as default)
You are getting a strange behavior. Let’s try with this workaround. Uninstall and delete the current Intel graphics driver and Realtek Audio drivers, restart the PC and install the latest Beta v.4474 Intel graphics driver.
Intel® Beta Graphics v.4474
Then, install the latest Realtek Audio driver provided with Asus support website.
Let me know how it works.
Not meaning to intrude here but I have a related problem that is somewhat similar but different. I have a working build and multiple non working builds.
Motherboard: Supermicro X11SSZ-QF
CPU: Core I7 6700T 2.80Ghz
Dual Monitors: Asus VE248 with display port audio.
Non Working does not recognize any sound
This may or may not be a related problem. Again I have several system without sound and one system with sound. On non working systems at initial build it would work until the first reboot.
I downloaded this 'Intel Display Audio Driver' Rev 188.8.131.525 but I can't get a system to recognize it at all.
I also noted that the word 'Display' is a hard search as Monitor or Graphics information comes up all the time even with a quoted ("display port") in the search and that coupled with the total lack of recognition of sound in the device manager made me wonder if the word 'display' is a proprietary name in the windows 10 device manager and it can't find it because when it reads 'display' it is looking for graphics monitor rather than sound. I know a bit of a reach and this guy must be in outer space but that is my thought process.
I tried the beta above with the same non result.
my PC is NUC6i7KYK,
my monitor is philips BDM4350UC
my system windows 10
my BIOS is the lastest version: KYSKLi70.86A , 0041 (2016/08/17)
my graphic driver is the lastest version: GFX_Win7_8.1_10_64_184.108.40.20681_KY
my audio reateck driver is AUD_Win7_8.1_10_220.127.116.1118
(i try the higher verision :realtek HD audio driver 18.104.22.16805 , it still didnt change the problem)
I have the same problem as alexg86 in displayport
(the scrreen off and back-->i use power button =close screen function or wait 5 mins the system screen off by itself)
1.if use the HDMI 2.0 connect to monitor, the audio is ok after screen off and screen back
2.But if use the displayport 1.2 connect to the monitor
the screen off and back, the audio is gone
i follow the alexg86 to disable and enable the High definition audio controller (not the intel audio controlker)
the audio will comeback
3.If i just turn off the power of the monitor BDM4350uc, then I turn on the power of BDM4350uc again.
In HDMI 2.0, it works fine, and the monitor will normally find and display.
In displayport 1.2, the monitor cant find the pc and keep in black. ( I need direct long push the power of the nuc6i7kyk to turn off the system,
then re-turn on the power of the nuc6i7kyk, the monitor works normal in displayport 1.2)
if need your help. ( have the beta version??)
sometimes, I need use HDMI 2.0 + displayport 1.2 the same time to connect 2 monitor,
so I need the well function of displayport.

If Display port is disconnected from the PC; you would not get video until plug DP port to PC and restart the PC.
There is a newer Audio driver for 6i7KYK NUC, it is version 7867.
Realtek ALC* Audio Driver (version: 22.214.171.12467)
If the problem continues, I would need more details of the issue. I understand, you have 1 monitor connected through the miniDisplayPort and it loses Audio after sleep mode. Is it correct?
When you say “the screen off and back, the audio is gone” you are referring come back from the sleep mode of the NUC or you manually or any TV setting to turn the TV off?
I have tested the 6i7KYK with the latest BIOS, Chipset, ME, Realtek and graphics drivers with Dual monitor and I am getting Audio (I used straight video cables: full HDMI and miniDP-DP).
I would be waiting for your results.
I noted you have 2 graphics drivers on your system. I suggest you to uninstall and delete Microsoft Basic Display Adapter driver.
The latest graphics driver for HD 530 is 4463 and Beta 4474 available in the link below:
The graphics driver handles the Audio if you are getting it from the HDMI or Display Port of the board ports.
If you are getting the Audio from the Audio jack ports of the board, install the motherboard Audio driver available in the link below: https://www.supermicro.com/support/resources/resource_drivers.cfm
Note: it is necessary to install first the Chipset driver of the motherboard.
