Upgrade Alsa (1.0.23) on Ubuntu Lucid Lynx 10.04
 | Ubuntu Lucid Lynx 10.04 is coming by default with the version 1.0.21 of Alsa so I decided to upgrade to the last version wich is 1.0.23. |
What is Alsa (Advanced Linux Sound Architecture) ?
According to Wikipedia, Alsa is a Linux kernel component intended to replace the original Open Sound System (OSS) for providing device drivers for sound cards. Some of the goals of the ALSA project at its inception were automatic configuration of sound-card hardware, and graceful handling of multiple sound devices in a system, goals which it has largely met.
Installation :
To do this, we must begin by determining our version of alsa as follows :cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.21.
To avoid problems during the upgrade of Alsa-utils, we need to stop it with the following command :
sudo /etc/init.d/alsa-utils stop
sudo apt-get -y install build-essential ncurses-dev gettext xmlto libasound2-dev
sudo apt-get -y install linux-headers-`uname -r` libncursesw5-dev
Then, we go in our personal folder and download alsa-driver, alsa-lib and alsa-utils :
cd ~
rm -rf ~/alsa* ~/.pulse*
wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.23.tar.bz2
wget ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.0.23.tar.bz2
wget ftp://ftp.alsa-project.org/pub/utils/alsa-utils-1.0.23.tar.bz2
After that, we create a new folder for the compilation and installation of the 3 files. Then, we move the 3 tar files that we just downloaded in this folder :
sudo rm -rf /usr/src/alsa
sudo mkdir -p /usr/src/alsa
cd /usr/src/alsa
sudo cp ~/alsa* .
Unpack the 3 tar files :
sudo tar xjf alsa-driver*
sudo tar xjf alsa-lib*
sudo tar xjf alsa-utils*
We compile and install alsa-driver :
cd alsa-driver*
sudo ./configure
sudo make
sudo make install
We compile and install alsa-lib :
cd ../alsa-lib*
sudo ./configure
sudo make
sudo make install
We compile and install alsa-utils :
cd ../alsa-utils*
sudo ./configure
sudo make
sudo make install
Then, we remove the 3 tar files in our personal folder that are not anymore necessary :
rm -f ~/alsa-driver*
rm -f ~/alsa-lib*
rm -f ~/alsa-utils*
Then, just restart your computer and your alsa version should be 1.0.23!
You can verify that you have now indeed have this version of alsa :
cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.23.
Compiled on May 2 2010 for kernel 2.6.32-21-generic (SMP).
Just to be sure everything is well configured, execute this command :
sudo alsaconf
and reboot again!
