I had the same issue. Dummy Output after installing 12.04. Alsa force- reload solves the problem but it ruins my wi-fi connectivity somehow. After force-reload my wifi device is fine for some time and then all of a sudden decides to "de-authenticate" the network. After that it would not connect to the wifi network no matter what. After reboot it's working fine until I do force-reload of alsa. Then I decided to try Oleg Cukanov's solution. It works as a charm. My config file had "options snd-hda-intel model=generic" in it. After changing it to "options snd- hda-intel model=auto" the sound and the wifi are working properly (for now).
