I've updated the driver for Ubuntu 12.04 Lucid too. I don't have that version so would anybody test it? Download from here: https://launchpad.net/~c4pp4/+archive/test/+files/lenovo-conexant-dkms_12.11.28.1_all.deb

and of course you have to remove all the previous workarounds for crackling sound:
sudo update-rc.d -f amixer-master-mute remove
sudo rm /etc/init.d/amixer-master-mute
sudo rm /etc/pm/power.d/intel-audio-powersave
