I have the same problem and I also have an Asus K42jr with lucid. I have tried compiling the latest alsa driver (1.0.23) but nothing changed.
I even changed /etc/modprobe.d/alsa-base.conf, added "options snd-hda- intel model=model"(I tried every model alsa supported, as listed below) to the last line. But that didn't seem to help either.
