OK, then the normal jack detection doesn't work with this machine, as it seems. You can try the above to all pins for checking if any of other pins reacts to the headphone jack.
No luck I'm afraid - none of the other pins seem to react to the headphones. Is there anything else you can think of that I can try tomorrow?
Well, it might be notified via GPIO. Try to read GPIO pins except for GPIO0. That is, set the all unmasked, the direction to READ.
hda-verb /dev/snd/hwC0D0 GPIO_SET_MASK 0x3f hda-verb /dev/snd/hwC0D0 GPIO_SET_DIR 0x01
Then read the values before and after the jack plug / unplug:
hda-verb /dev/snd/hwC0D0 GPIO_GET_DATA 0
BTW, I'll be in a short leave in the next week, so the reply will be delayed.
