Hello,
My NUC D54250WYK play intel sound on itself even out.
When opening the box, I heart it playing intel sound one time.
I began to prepare it : open it, put ram, flash disk, but not tested it yet as I didn't have adaptor from miniDisplayPort to VGA.
This morning, it plays the same sound one more time.
I don't understand why as it's not on and not plugged to anything (even electrically) yet.
Thanks.
