Anyone get the feeling that the people voting ”no” on this poll are flat out lying to try and compensate for all the “yes” votes, or that they simply refuse to check for the issue using all the video examples given in the thread? Sorry, I’m just not buying that some machines do it and some don’t. That would mean it’s 100% a hardware issue. If that were the case Apple would really be in deep and I’m certain they would have said something by now.
No offense to anybody who voted no, but my guess is they probably don't want to hear it or don't know how to check for it. At this point, I'm very confident that 100% of the machines are affected by this issue. There is no way people go through numerous replacements and they all making the popping sound. And this is from Apple Stores all over the world.
