There is iQuik audio ppa for lucid that updates the alsa user space to
1.0.24.

There is an alsa backports kernel module 1.0.23

In proposed lucid:-
linux-backports-modules-alsa-lucid-generic

I would try the backports module first (1.0.23), the iquik ppa was
recommended for getting HDMI audio working etc..
