Summary:                    Simultaneous sound from speakers and headphone
Description: 
I cannot ear headphones without having sound from front speakers
simultaneously.
Volume of headphones is adjusted by front speakers and when muting front
speakers also mutes headphones.
(in MS Windows, inserting headphones automatically disables sound from
front speakers)

I've tried different alsa versions and then models from realtek patch, but
to no avail. Same problems - switching between headphones and laptop
speakers. Option "test" gives the most complete controls, so it seems
other models simply don't match my hardware.

Since it's 10 years last time I coded anything - could somebody point me
in the right direction, I would be more than happy to help.

I have the same issue with a Sigmatel STAC9200.  While playing around with
the code, I sumbled across a (too simple) fix:

AC_PINCTL_OUT_EN);


This works in that if I insert headphones after the driver is loaded, the
speakers are correctly muted, and sound comes from the headphones.  If I
remove the headphones, sound comes from the speakers again.

The problem with the above fix is that I end up with both master and
headphone controls in alsamixer.  Muting either will mute the headphones
or speakers depending upon which is active.  Adjusting the volume of
either also affects both outputs.

Any advice on how to properly avoid the calls that generate the extra
headphone controls for my hardware would be appreciated.
