Hello, Since a couple of days I'm noticing a popping sound during audio playback through my external speakers. That means when playing back a video or music through iTunes, basically always when there's audio playing. I'm in the process of figuring out if it also happens on my regular integrated speakers. My MBP is the recently released 15" Core i7 model. Only thing I changed is I added an Intel SSD. Any thoughts as to what it can be? Or where to start looking for a solution? Thanks in advance!
