I just needed drivers, libs and utils and downloaded and extract the latest
from http://www.alsa-project.org/main/index.php/Download
to /usr/src/alsa/

check that the sources for your kernel are installed, install them if needed

apt-get source linux-source-'uname-r'

if you build your own kernel you should have your sources still available

change directory to /usr/src/alsa/alsa-drivers* and run

./configure --with-cards=hda-intel --with-oss=yes --with-sequencer=yes && make && make install

change directory to /usr/src/alsa/alsa-libs* and run again

./configure && make && make install

change directory to /usr/src/alsa/alsa-utils* and run again

./configure && make && make install

run
