In my case after "sudo apt-get install module-assistant" and "module-assistant a-i alsa-source" i have no sound. Then i add this line - options snd-hda-intel model=6stack-dig in the end of /etc/modprobe.d/alsa-base -> restart pc and sound appear :). I have Realtek 861 integrated soundcard. This is list of options after model:
