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

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).
