I have the D54250WYK NUC, with windows 7 and 12.3 stable release XBMC. I've noticed a background audible low frequency hum that is unique to the NUC's HDMI connection through my Pioneer 1222K receiver. I find this odd for many reasons.
For example, its most noticeable when using a mouse to navigate XBMC's menu's. My first notice was when navigating the settings submenu. If the cursor was placed on the left side buttons, there would be no hum, if the tip of the cursor touched the first pixel of the right hand section, the hum would begin. The hum will modulate up and down as I move the cursor around the right side of the screen. Very odd.
Its also noticeable when using a remote, when navigating menus, selecting a movie for example the hum will oscillate to varying degrees as focus jumps from menu item to menu item.
I lean toward a bad part or design flaw in the NUC, but would like to know if anyone has had the same experience.
I'm using the mini-HDMI connection. The hum was only noticeable once I installed the NUC in my screening room, where Klipsch speakers and multiple subs reveal all.
