It seems that Apple sent the latest MacBook Pro update with a few gremlins left to work out. Last month, it was Core i9 damper performance, now, some owners are cracking sound through the built-in speakers.
When using up to $ 1300 on a laptop, you expect it to work flawlessly from day one and hopefully for your entire life. With the recently released version of the 2018 MacBook Pro it's certainly not the case with another error, this time with audio output, which appears to some owners.
Last month, it was discovered that the Core i9 MacBook Pro experienced cooling problems that killed performance. Apple investigated and discovered that it was a performance problem and issued a solution. Fortunately, all that was needed was a firmware update. But now there is another problem and it can not be so easy to solve.
As MacRumors reports, multiple videos of MBP owners display audio through the built-in speakers on the laptop and experience crackling sounds. The severity varies greatly, but you can not fail to notice what the music plays.
It does not break apparent software or service related as it is experienced when audio is played through iTunes, YouTube, GarageBand, or when you run Windows through Boot Camp. The best guesses for the reason for now are radio interruptions through lack of shielding in MBP, audio drivers do not work properly, defective speakers or the new Apple T2 chip, including the audio controller for MacBook Pro.  Owners (and Apple) hope there is a problem that can be solved with a software update. If there appears to be a lack of shielding or defective T2 chips, then Apple is a major headache, which probably has to offer free repairs to anyone experiencing cracking.
Apple sees no doubt the error, which does not seem to be so widespread at the moment. Could it just be a bad series of hardware?
