Enable sound on RS780 Azalia controller

I am writing this post because my friend asked for help installing Windows on a laptop, then I installed it, but suddenly there is an error, can not be installed because I suggest to install Ubuntu and found that he agreed, after I installed Ubuntu and found his voice codecs another problem, sound not detected in Ubuntu. But I believe every problem in Linux must be a solution … hehehehe … great Linux …

Then I searched on Google and got the following link http://ubuntuforums.org/showthread.php?p=7231465 # post7231465 (Thanx’s)
After I opened and read, to add some code in /etc/modprobe.d/alsa-base.conf

Here are the steps:

Sign in gnome-terminal, type the command:
andriest@FOSSil:~$ sudo nano /etc/modprobe.d/alsa-base.conf

Add the following code:

options snd slots = snd-hda-intel, snd-hda-intel
options snd-hda-intel model = dell-m4-2
# 5Dex.Jpa__qQ4asA: SBx00 Azalia (Intel HDA)
alias snd-card-1 snd-hda-intel
# L4dC.vfAxXUx5zd4: RS780 Azalia controller
alias snd-card-0 snd-hda-intel

When finished press Ctrl + X >> Enter then restart the computer and please enjoy the music and videos from your laptop …
Do not ever think that Linux is hard … Go Open Source…!!!
