Thanks for joining the NUC community.
I understand you are not getting DTS audio pass through via Display port to HDMI.
I just checked with our engineering team and DTS format should work on this NUC model.
You may need to update NUC BIOS version 0028

Also, the latest video drivers for your graphics controller, this will load latest HDMI codec:
Please take a look at this URL for more information: No DTS Audio output in Windows 7? - Super User
Thanks for the fast responce.
I think you pointed me to the wrong update for the videodriver or will these also work on the NUC D54250WYK?
Anyway, I updated from Bios 0026 to 0028.
And installed the latest video driver; https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=24224&lang=eng&ProdId=3744
I will check if it worked when I get home.
