Possibilities:

Try installing the linux-backports-modules-karmic-generic module:
$ sudo apt-get install linux-backports-modules-karmic-generic
Shut down (not just log off or restart) and boot back up & try.
If that still doesn't work, you might try installing:
$ sudo apt-get install linux-backports-modules-alsa-karmic-generic
to see if that does the trick.
