Hello, Over the past few months or so, I've been noticing a sound, much like a buzzing, coming from the left speaker area of my computer. It seems to be near the area where I plug in the charger. The sound is not terribly loud, but when it's quiet in my surroundings, it becomes quite evident. I'm not talking about an audio-related issue, but I am just unsure as to what may be causing the sounds and whether or not I should be worried. Can anyone share any advice? Thanks!
