Comment 1 for bug 159045

sound isn't working for me either, I'm running gutsy-i386. The following lines workaround my problems:

wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.15rc3.tar.bz2
tar -jxvf alsa-driver-1.0.15rc3.tar.bz2
cd alsa-driver-1.0.15rc3/
./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
sudo reboot
