Here are Marius' steps slightly modified. This should make patching the alsa source and installing the new modules fully automated -- just copy and paste these commands into a terminal:

sudo apt-get install alsa-source
cd && mkdir alsa-patched && cd alsa-patched
tar -jxvf /usr/src/alsa-driver.tar.bz2
cd modules/alsa-driver/
wget -O alsa-kernel/pci/hda/patch_analog.c
./configure --with-cards=hda-intel && make
sudo make install
sudo cp ./modules/snd-hda-intel.ko /lib/modules/$( uname -r )/ubuntu/media/snd-hda-intel/
sudo depmod -a
