Bluetooth audio choppy/skips on El Capitan
I have found yet another unofficial solution! it worked for me and i hope the same to you. i believe the macbook utilizes bluetooth in the background for handoff and FaceTime. i believe it searches occasionally for data or cues that are sent from secondary devices or stays quietly paired with a device you may already have (causing gaps in bluetooth connectivity). i signed out of FaceTime (disabling it) and disabled handoff. i have an iphone, and it seemed to create some kind of bluetooth interference. try this and see if it doesnt help or solve the issue
