I have an HP Pavillion dv7 and Kubuntu 12.04. I performed update and upgrade of the system and linux-generic, linux-headers, linux-image, linux-libc-dev changed from 3.2.0.77 to 3.2.0.79 version. After that my soundcard is not recognized (obviously I get no sound). I can not find a way to reverse this upgrade.
