Thank you for contacting Intel Communities.
The audio features on Intel® NUC Kits may vary depending on the model number that you will get. Below is a screenshot of the Realtek HD Audio Manager on an Intel® NUC Kit NUC6i3SYH:
Further details/features of the audio subsystem are available in the Intel® NUC Board NUC6i5SYB and Intel® NUC Board NUC6i3SYB Technical Product Specification > Page 28, item 1.9
For newer versions such as the Intel® NUC Kit NUC7i3BNK, the "Sound Effects" tab is no longer available, you can check this thread for further information.
I hope this information helps.
