The Surface Pro 2 and 3 have a strage frequency response and miss most
of the bass. I discovered connecting the HP out to the main DAC fixes
this. Maybe the other is mono or whatever strangely mixed signal for
the built-in speakers?
I later noticed the Lenovo Ideapad 720S (AMD) exhibited the same
problem, so this may be a more wide-spread general bug w/ Realtek
codecs and the hda_auto_parser, ...

Usually in a case like this, we provide a fixed wiring by a static DAC
table, or do some other tricks instead of directly writing a verb.
Could you give the alsa-info.sh outputs from those?
thanks,
