I can't figure out what is causing a very high pitched frequency to emit through my Right monitor only. It's very distracting. It is in a random pattern, on and off every few seconds. It's like morse code... sometimes it's longer (2-3 seconds), sometimes short (1-2 seconds), in intervals of 1-4 seconds. I can hear it from several feet away, and when you put your ear up to the speaker itself it is very evident. I've tried different things but I still can't get rid of it. I use the speakers with my DAW (they are currently hooked up to my laptop via a mini-stereo out to 2 mono 1/4" jacks). I have a feeling it is something to do with my laptop. Any thoughts on this?! It is incredibly annoying, and I just started noticing it a couple weeks ago, though I've had them for many months. Thanks.
