I have bought and installed a new D54250WYKH this weekend. The problem I have since the first startup of the NUC is that it gives weird noise through my speakers.
This is not a windows related problem cause it starts allready when I power on the NUC.
Philips 40PFL9705 -> gives noise
Rotel RSP-1572 -> gives noise
Tried 2 brand new HDMI cables. 1 from 10 euro and 1 from 50 euro's. Same result. Tried the NUC most far away from my equipment. No result. I used a HTPC with an AMD HDMI 5450 card and never gave me any problem but I wanted a smaller HTPC.
Tried all BIOS versions. I hope there is a solution else it's going back to the store...............
