Buzzing sound from left speaker

[sketchygio]

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!

If you're concerned, have it checked out. Can't hurt.

what computer are you using?

I had an issue with my 2008 MacBook Pro (unibody), which turned out to be a defective fan located in the upper left. I'd posted a response to a thread awhile back, but there were some early issues with the fan blades being unbalanced or something, I can't remember exactly. The noise would be barely perceptible just after startup (while the computer was still cool), but would get louder as things heated up and the fans spun faster. I used smcFanControl to manually force the fans to spin faster, which reproduced the noise. Try a search around the forums for others who have done similarly.

After contacting AppleCare, they issued me a full replacement. Sorry I can't be of more help. Good luck!
