I've always been a Macbook Pro user, and tend to get a new one every 3 years or so. Just did this about a month ago. Great machine, with one nagging issue. The audio will just randomly cut out altogether while I'm watching a video source, be it a YouTube video, or live sports (baseball of late), and any kind of a video from Facebook, etc.
So I Googled to see if it was a common problem, and if there was an easy solution. Appears to be yes, it's a common problem, and no, it doesn't seem to have been properly diagnosed and solved yet. https://discussions.apple.com/thread/8466406
Should have mentioned that it's annoying as fuck.
