@WereCatf It is very annoying, though, even if it's still functioning properly.

So, I just got my packing from Onion yesterday and testing out one of my Omega2+'s in the Arduino Dock that I have and I noticed right away that it is emitting a very high pitched consistent noise. I tried the dock with both of the Omega2+'s that I have and always got the noise. I not get the noise with either of them in the Power Dock that I have. I'm assuming that this isn't normal. Suggestions? Here's a video file to show you what's going on. I'm powered the dock with wall wart style power supply to a USB-micro connection that I tend to use for a Raspberry Pi. Nothing else is connected.
