Popping sound and buzzing from speakers
I've had my Macbook air for around 2 years now, and recently there is a distinct pop sound whenever audio begins to play, even when the speakers are muted. The pop is followed by this faint buzzing sound that disappears when audio stops playing. The sound comes from the right side of the laptop. I've tried changing the audio balance between left and right, but the buzzing sound is still there. I have no problems when I have headphones plugged in. Any help?
