I think this bug is related to this one:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/418617

It is more detailed and suggests the source of the problem; it also seems that the bug occurs in many more machines.

The suggested fix there (for a Dell XPS) is to install linux-backports-modules-alsa-karmic-generic or linux-backports-modules-alsa-karmic-generic-pae (depending on your kernel).

However, this did not work for my Lenovo X300, so it's not resolved yet, but maybe somebody can use the information to construct a solution for the Lenovo's as well.
