when I plug in my headphones, they do not work. This happens with the 4
kernel on ubuntu, arch, fedora. Ubuntu 14.04 lts is fine and so is
fedora 22. I noticed if I plug in my audio extension cord in the left
jack and plug my headphones in the middle jack, they work(ubuntu
15.10+16.04,fedora 23 and arch).

You also need to add "Speaker+HP" to slaves of virtual master

After the driver rename the shared volume control"Speaker+HP" , you need
to change pulseaudio conf to avoid headphone mute the shared volume
control similar to
