How to install Intel High Definitions Audio

Type lspci in your terminal: if you have an output like this:

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

look at this guide to install correctly your card on your Ubuntu:

1- first of all install the build-essential package: sudo apt-get install build-essential ncurses-dev

2- download the alsa-driver from: http://www-old.alsa-project.org/alsa/ftp/driver/
alsa-lib from: http://www-old.alsa-project.org/alsa/ftp/lib/ and
alsa-utils from: http://www-old.alsa-project.org/alsa/ftp/utils/

3- then move to the directory in which you have downloaded the 3 files and extract them in /usr/src/alsa:
sudo mkdir -p /usr/src/alsa
sudo cp alsa-* /usr/src/alsa sudo tar xjf
alsa-driver-1.0.14rc1.tar.bz2sudo tar xjf
alsa-lib-1.0.14rc1.tar.bz2sudo tar xjf
alsa-utils-1.0.14rc1.tar.bz2
cd /usr/src/alsa

4- compile and install alsa-driver:
cd alsa-driver-”version”rc1 (subs version with your version)
sudo ./configure –with-cards=hda-intel
sudo make
sudo make install

compile and install alsa-lib:
cd ../alsa-lib-”version”rc1
sudo ./configure
sudo make
sudo make install

and alsa-utils:
cd ../alsa-utils-”version”rc1
sudo ./configure
sudo make
sudo make install

5- now you have to edit the /etc/modprobe.d/alsa-base file and add in the last part of the code this line:
options snd-hda-intel position_fix=1 model=3stack
now your intel HDA must be correctly installed!!!…. have fun!!!
