Been reading a few threads here and some people have the cracking/popping speakers, most of them were with the MacBook Pro's prior to the unibody but a select few were using the unibodies. Is this a hardware defect? Few threads stated that the cracking/popping resulted after installing a certain version. Just wanted to clarify because it's annoying me. If it is, I guess 3 things "wrong" warrants an exchange. (speaker issue, MBP not leveled correctly, and "grinding" SuperDrive)
