How to make the sound card work in asus N53 j laptop

My issue was that the sound card worked with headphones but not with the internal speakers my laptop has.

After some Google search I came across with this blog: http://blog.tersmitten.nl/archives/1082/comment-page-1#comment-3371

I did what the author said there but get no results, but this gave me some clues where to find.

Then I looked at https://help.ubuntu.com/community/HdaIntelSoundHowto and followed all the guidance this documentation has.

This how to assumes you have the latest alsa drivers installed.
So, what i did was:

• Open the file alsa-base.conf located in:
  

  /etc/modprobe.d/

sudo gedit /etc/modprobe.d/alsa-base.conf

• Then add the next two lines to the end of this file:

options snd-hda-intel model=auto
options snd-hda-intel probe_mask=1

Workaround:

• instead of the two lines above add only :

options snd-hda-intel model=auto position_fix=0

to the end of this file

• save the file, close it, reboot yor computer

That's it.
