It seems Apple shipped the latest refresh of the MacBook Pro with a few gremlins left to work out. Last month it was the Core i9 throttling performance, now some owners are experiencing crackling audio through the built-in speakers.
When you spend upwards of $ 1,300 on a laptop, you expect it to work flawlessly from day to day and hopefully for its entire lifespan. With the recent release of the 2018 MacBook Pro, that's certainly the case with another fault, this time involving audio output, appearing for some owners.
Last month it was discovered that the Core i9 performance. Apple was examined and discovered. Thankfully, all that was required is a firmware patch. But now there's another problem and it can not be so easy to solve.
As MacRumors reports, multiple videos are appearing of MBP owners playing audio through the built-in speakers on the laptop and experiencing crackling sounds. The severity varies greatly, but you can not fail to notice it as the music plays.
The crackling does not seem to be software. It is played by iTunes, YouTube, GarageBand, or when running Windows via Boot Camp. The best guesses for the cause of so far include the following: Apple T2 chip, which is among the things that are the audio controller for the MacBook Pro.  Owners (and Apple) will be hoping it's a problem that can be fixed with a software update. T2 chips then that's a big headache for Apple who would probably have to offer free repair to anyone experiencing the crackling.
No doubt Apple is looking into the fault, which doesn 't seem to be that widespread at the moment. Could it just be one bad batch of hardware?
