Sometimes it works, sometimes it doesn't. If I play with the alsa mixer settings and pavucontrol I can get it to work. I've noticed that putting the computer to sleep sometimes allows it to detect headphones for a bit, but doing things like upgrades resets it. I can't quite figure out what works cause sometimes just restarting it makes it work suddenly.
Also affects me. I am using:
Operating System: Ubuntu 16.10
Kernel: Linux 4.8.0-34-generic
Dell XPS 15 9550
