In theory, , the driver can automatically mute IEC958 Playback Switch
(turn off the red light for power saving) when you plug/unplug the
side jack which share with spdif

speaker test or pulseaudio expect the "front volume" control the front
jack (i.e. your HP jack) in surround 40 , 51 or 71

change one of the unused pin to  speaker pin by hda-jack-retask

http://thread.gmane.org/gmane.linux.alsa.devel/92229

assign hp to get dac 0x02 instead of speaker_pins[0]

you have to assign your 0x14 speaker and one of the unused pin of  to
spec->extra_out
and increase spec->speaker_outs from 1 to 2
