I was working in garageband, listening to something I had just recorded when I heard a pop. My recording stopped playing, I began to play it again, and only my right speaker works. I tried listening to other music(on youtube) to see if somehow garageband had set the controls to right speaker only, but it looks like my speaker doesn't work. I'm not sure if my speaker blew out? Can I test it somehow? Does anyone have any similar experiences? What should I do? edit: they just started making popping noises. I've haven't been on max volume throughout any of this, actually. If I put the volume on one, they start making popping noises.
