I have a new 2016 MacBook Pro with TouchBar that I bought earlier this year and at random times I will hear a semi-loud pop come from my MacBook Pro, not sure if its from the speakers or what it is, but it happens every now and then randomly. Anyone else notice or hear this? Also, after using computer for awhile the volume scroller shows and looks like its working and shows on my screen, but the volume isn't actually fixed. Only way to fix is to restart my machine. I have tried resetting my PRAM and SMC and still have same issue. Anyone else having these occur?
