I seem to be seeing this same behaviour on my dell studio 15. Sound worked correctly on Hardy Heron. Right now ALSA sound does not work (clicking and crackling) but an OSS sound test does work. If I reboot back to the Hardy kernel which is still installed on my system sound does work, with everything else the same. So this seems it must be a kernel issue with alsa.
