Hello Mkholov, according to the TPS of this NUC it does support the following audio technologies:
• AC-3 - Dolby* Digital
• Dolby Digital Plus
• LPCM, 192 kHz/24-bit, 8 Channel
At this moment, some products are experiencing audio issues related to HDMI. You would be able to find additional information on the following link. The information provided was given by an Intel Engineer. https://communities.intel.com/message/218663#218663
We are working on getting a new BIOS updated in order to solve this issue. Customers with OEM systems have been able to fix the issue, updating the BIOS to the latest version available and with the installation of the latest graphic drives.
Unfortunately, I believe the link you provided describes a different issue than the one I am reporting here. I am unable to get DTS-HD passthrough working at all rather than having it drop out, and there is only one graphic driver and one bios version available for the DN2820FYK that I can see.
Any other options/suggestions?
I'd like to replicate the issue. To help me configure a system in our lab to match yours as closely as possible, can you complete the configuration checklist at http://communities.intel.com/docs/DOC-21212?
NUC Model: DN2820FYKH
Serial No: G6YK3520xxxx
Bios: Latest (15)
OS: Windows 8.1 Enterprise
Monitor: Marantz 1503 AV Receiver (supports HD Audio and works great with the older Celeron NUC) / Samsung 1080p TV)
Graphics : Latest (from the 1/8 Driver Bundle)
Graphics port: HDMI
Graphics converter: None
LAN device: Wired
LAN driver version: Latest (from 1/8 Driver Bundle)
LAN connectivity: Gigabit
Memory: 4GB Patriot (PV34G160LC9S)
SSD: Toshiba 500GB SSHD (MQ01ABF050H)
Software: XBMC (latest overnight build). When connected to the AV receiver DTS-HD nor TrueHD is listed as being supported. Which clearly points to a hardware/firmware/driver issue and not the application.
When DTS-HD or TrueHD is the selected audio track there is no audio although the image appears fine. Switching the audio track to DTS and the audio works.
There seems to be a lack of understanding from the Intel representatives here.
So to clarify, the lack of DTS-HD is likely due to no Management Engine Driver available for this version of the NUC.
In all other products containing Intel HD Graphics, the additional Management Engine Driver is required to enable Protected Audio Path (PAP) which Windows requires to pass HD audio.
Here is the driver for Ivy Bridge NUC's
Here is the driver for Haswell NUC's
Looking at the driver list for the DN2820FYKH there is no Intel Management Engine driver available:

I'm facing this issue too. DTS HD isn't listed as supported format under control panel. DTS HD passthrough doesn't work. Details below:-
NUC model: DN2820FYKH
Bios version: 0021
OS: Windows 8.1 Professional (64-bit)
Graphics port used: HDMI
Graphics driver: Intel HD Graphics Driver Version 10.18.10.3383
Graphics converter used?: No
AV receiver used?: Denon AVR-X1000
Software: Plex Home Theatre (18.104.22.168-bde1e61d)
DTS HD passthrough via WASAPI or DirectSound doesn't work. Video playback at 1-2 fps and no audio when set to DTS HD. Works well when set to DTS.
Note that symptoms are very similar to the Netflix issue which I am facing. Other NUC/Win 8 users are facing this too:
Basically, NUC users (not limited to DN2820 users) cannot get Netflix metro 8.1 app to work with Dolby Digital Plus 5.1. This will result in stuttering video at 1-2 fps and no audio. issue is resolved when set to stereo.
I hope that intel can address these problems as soon as possible.
update: I just updated the bios to ver 0025 and can confirm that the problem still persists.

I just received my new NUK 2820 FYKH. And installed Windows 8,1, 8 gb mem and a ssd disk .
Unfortunately I have the same issues w the sound as the others here !!
Have upgraded the audio HD drivers, but still no sound via HDMI cable . All other machines like Ipad and Acer works towards my Pioneer receiver . Now It reads No device connected. This is a large disappointment as the NUC should be used as a media centre, streaming movies and netflix etc. according to the ads.
Now I need a quick fix or I will have to return the device to the seller w a claim that it dont work ..
What are your suggestions.
waiting for ur response..
att a siu report.
