Same symptoms here with a Dell laptop (Precision M6400) with Kubuntu AMD64: - no sound with the default kernel in Jaunty (2.6.28-11-generic) - perfect sound with the default kernel in Intrepid (2.6.27-11-generic) ( I still have installed, easy to choose upon boot)
I tried to install Pulseaudio, and reached a point where there is some activity reported with playback volumes of the padevchooser systray icon (apt-get install padevchooser + Atl+F2 "padevchooser"), but without any sound (see http://ubuntuforums.org/showthread.php?t=1136724) Also,it is not clear to me if a stock Kubuntu is using pulseaudio or not, and if there is any gain to use it.
