added this option in alsa-base.conf:
options snd-hda-intel model=thinkpad
Headphone jack WORKING NOW!!!
HOWEVER, the built in mic is not working. Only the external mic works (opposite as when no option was added to the alsa-base.conf) (I tried with all the three models Daniel T Chen suggested -> same result for the 3)
