Not a neetbook, two jacks, one Mic, and one S/PDIF

1) Nothing plugged in:
./hda-verb  /dev/snd/hwC0D0 0x14 SET_PIN_SENSE 0
nid = 0x14, verb = 0x709, param = 0x0
value = 0x0

./hda-verb /dev/snd/hwC0D0 0x14 GET_PIN_SENSE 0
nid = 0x14, verb = 0xf09, param = 0x0
value = 0x7fffffff

2) Headphones plugged in in S/PDIF
./hda-verb  /dev/snd/hwC0D0 0x14 SET_PIN_SENSE 0
nid = 0x14, verb = 0x709, param = 0x0
value = 0x0

./hda-verb /dev/snd/hwC0D0 0x14 GET_PIN_SENSE 0
nid = 0x14, verb = 0xf09, param = 0x0
value = 0x7fffffff

3) microphone plugged in 'Mic'
./hda-verb  /dev/snd/hwC0D0 0x14 SET_PIN_SENSE 0
nid = 0x14, verb = 0x709, param = 0x0
value = 0x0

./hda-verb /dev/snd/hwC0D0 0x14 GET_PIN_SENSE 0
nid = 0x14, verb = 0xf09, param = 0x0
value = 0x7fffffff
