Hello Moorstream, I am sorry to hear you are having problems with your NUC and the graphics driver.
I would recommend you installing the latest graphics driver available from the Graphics download center.
If operating system is 32 bit based:
If operating system is 64 bit based:
I know you installed the latest driver bundle; however I would like you to try installing this version.
Thank you for your answer. I have done the following steps:
- I installed the 64 bit driver from the link you provided and restarted. There was no difference, the HD audio did not work.
- I uninstalled the Intel driver and the Realtek High Definition Driver, and restarted. I then installed the 64 bit driver from the link you provided and restarted again with the same result.
- I noticed that I could not see the Encoded Formats when checking properties of the driver and that I had the Microsoft High Definition Audio driver installed. I then installed the Realtek High Definition Driver again from this link: https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=24004&lang=eng&ProdId=3742 , restarted and now I am back where I started, not able to play HD audio.
The tests I did in XBMC was both with the DirectSound and the WASAPI setting and I did perform the speaker configuration.
A few questions:
- Could it be a BIOS/UEFI settings?
- Should I use another source for the Realtek High Definition Driver?
- The HDMI cable is connected to an Onkyo TX-NR616 receiver, could this be an issue. I suspect not though.
I include the dxdiag output of the current configuration below, perhaps it will help. I am not sure I am able to create one in English though:
Best regards, Moorstream

I have now tried your suggestions.
- I installed the driver, unfortunately it did not fix the issue.
- I also tried the NUC without the receiver. Still the same, I did not get the HD audio formats working. All other formats worked, just as via the receiver.
- I loaded defaults in my UEFI, also without result. I tried to uncheck legacy boot also without result.
I found another thread with the similar problem:, no DTS-HD audio but for another model: DN2820FYKH DTS-HD?
Do you think it is the same problem?
Do you need some more information about my system for troubleshooting?
How should I proceed?
Moorstream it could be that your issue is related to that other thread. However it take me to this information provided by an Intel engineer
Could you please check this forum?
I have read these threads and I do not recognice these problems.
I never loose any audio, DTS and Dolby Digital is always working regardless of changing input, turning off display etc. The HD sound systems never work, either after reboot or when coming back to the NUC or having other components turned off or at different input.
Also DTS passthrough is working, it is TrueHD and DTS-HD that never works.
When checking this thread again, DN2820FYKH DTS-HD?, it seems that this model does not at all support DTS-HD and that the specification for that model was wrong. Is it the same for the for the D54250WYK model?
Please, how should I proceed?
Best regards, Moorstream
I also use XBMC, if you set XBMC to passthrough HD audio, the NUC with windows 8.1 plays DTS-HD as DTS, if you don't set XBMC to passthrough HD audio, DTS-HD is played as PCM because is converted before it's played,the HD audio passthrough doesn't work yet in windows 8.1, It's work fine in linux, XBMC on ubuntu does passtrought DTS-HD fine, I think there is a bug in the windows 8.1 driver.
