@NoOp: In my PPA, I pulled in a couple of patches from the ALSA mailing list to make the sound on my Vostro 1015 work, and the author of those patches has the same model as well. Those patches were integrated into the 1.0.22.1 release of ALSA, which in turn has been integrated into linux-backports-modules-alsa-2.6.31-20, rendering my PPA obsolete. (This is what I believe LProf meant to say, and why I marked this bug fixed.)

And yes, merely installing it was enough to make my sound work. Others needed to add the workaround in #54, because their model and make were different. This could possibly help you, but since your card seems to be correctly recognized as the 'Conexant CX20583 (Pebble HSF)' already, I don't know if it will really help.

The package from ppa:ubuntu-audio-dev is updated daily with as of yet unreleased code from the ALSA developers, so that is what you should use if your sound still does not work.

There's another, manual workaround in #15-16, which hopefully works with your model as well. Daniel's suggestion in #8 might help as well.
