Default [Q] Franco kernel and autoplay headset

A few days ago I flashed Franco kernel r32 and first of all, battery life is much better!

But also since a few days, music is not played automatically when I plug in my headset. I used Smart Connect, it starts whatever player I choose, but music is not started. I am not sure whether this is kernel related.

Does anybody have a working setup that when they connect a wired headset, the music plays automatically?

Btw. I have Xposed and GravityBox installed as well, but could not find a solution there.
