Sound Problem in compaq 510 at ubuntu 9.04

solution to problem (as the problem is only with jaunty .. both intrepid and karmic workd fine i think a sol i enough to close the bug)-

To do this, we must begin by determining our version of alsa as follows :

cat /proc/asound/version

Advanced Linux Sound Architecture Driver Version 1.0.18rc3.

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
We must then install the necessary tools to compile along with the kernel headers :

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-1.0.20.tar.bz2
wget ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.0.20.tar.bz2
wget ftp://ftp.alsa-project.org/pub/utils/alsa-utils-1.0.20.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 1.0.20!

You can verify that you have now indeed have this version of alsa :

cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.20.
Compiled on May 9 2009 for kernel 2.6.28-11-generic (SMP).

Just to be sure everything is well configured, execute this command :

sudo alsaconf
