RE: XPS 15 9560 does not recognize headphones plugged in

I have got the same problem. The solution is easy, just go to your task manager-- startup, find HD Audio Background Process & Realtek HD Audio Manager, disable them and restart your XPS 15, problem fixed then.  Hope this will help you out as I have tried almost all the way posted on forum like updating the driver or clean install the win10, finally find the problem is about these 2 apps.
