Installing official linux-backports-modules-alsa-lucid-generic package doesn't fix this problem :( Sound works fine with Ubuntu 11.04, so installing linux-image-generic-lts-backport-natty package from ppa:kernel-ppa also fixes this problem. SOLUTION for Ubuntu 10.04 LTS: Please update linux-backports-modules-alsa-lucid-generic package to include the latest ALSA drivers (1.0.24) from http://alsa-project.org or include linux-image-generic-lts-backport-natty package into official Ubuntu 10.04 backports or updates repository. ALSA 1.0.24 released on 2011-01-30, see http://alsa-project.org/main/index.php/Changes_v1.0.23_v1.0.24 for list of improvements. I found a similar bug #582506 but with different audio hardware. I think the latest ALSA drivers would fix that bug also.
