I've fixed sound problem following these steps ( https://answers.launchpad.net/ubuntu/+question/64930 ):

cd alsa-driver-1.0.19
./configure --with-cards=hda-intel --with-kernel=/usr/src/linux-headers-$(uname -r)

sudo make install
cd ..

cd alsa-lib-1.0.19
./configure
make
sudo make install
cd ..

cd alsa-utils-1.0.19
./configure
make
sudo make install

# Finally, edit file alsa-base.conf

sudo gedit /etc/modprobe.d/alsa-base.conf

# Add these lines:
options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=dell-m4-1
options snd-hda-intel enable_msi=1

Built-in speakers and headphones work. However, I didn't test mic.

Between some updates I need to do all process again (I don't know if there another procedure).
