Headphones does not work, but speakers do.

Alsamixer and sound settings recognize headphones, and everything seems to be ok from hardware side but it is not.
Here is my ALSA information script: http://www.alsa-project.org/db/?f=a0a9cc2f95cb36e31e915f8a304851a462dc95c6
I did follow every single solution from here: https://askubuntu.com/questions/132440/headphone-jack-not-working and my headphones still do not work.
I'm Ubuntu newbie and I am starting to be a bit confused about this issue. Anyone can help me?!?!
