Hello feardamhan,
I sincerely apologize if you are having a problem with the DTS-HD audio format on your Intel NUC. There was misinformation in the NUC's specification - this NUC model does not support the DTS-HD audio format.
We are working to correct the specification. Let me know if you must have this audio format - we can offer a refund for your NUC so that you can get new product that does support DTS-HD.
Here is our contact information:
