--- Comment #9 from Masachika ISHIZUKA <ish at amail.plala.or.jp> ---
I'm using dell xps12 9q33.
I also had been suffering for a long time hiss, but was finally resolved.
For headset jack is marked with the microphone terminal, I add the following to
the /boot/device.hints as mic jack is recognized.

hint.hdaa.1.nid27.config="as=4 seq=0 device=Mic conn=Jack loc=Left ctype=1/8
color=Black misc=0"
