I have a 15 "MB Pro with Touchbar (2017). Everything has worked fine for almost a year, recently. Now that I use Bluetooth headphones with my external monitor (USB-C hub), the sound still jumps I have used AirPods with the same setup for a long time, and this started a few days ago. I've seen posts about resetting SMC, PRAM, etc., but nothing has helped. I've done a full recovery myself.
