I've only noticed this within the last day or two, I don't remember if it's always done this, but my DS is emitting a high-pitched buzzing noise. If I turn the volume all the way down it stops, but as soon as I bring it up a little bit, the noise comes back. I thought it might just be a certain game or something, but it happens with every one, and even during the menu screen. Like the dead pixel on my first one which I tried to ignore, I'm increasingly getting annoyed at the sound. Am I just a freak and do all DS's do this? Or is it cause for concern?
