I recently upgraded my Dell studio xps laptop (which shipped with 9.04)
to 9.10. I now have no sound.  No soundcard is detected:

2.6.28-16-generic is a jaunty (9.04) kernel, not an karmic (9.10) kernel:

<http://packages.ubuntu.com/search?searchon=names&keywords=2.6.28-16-generic>

The latest karmic kernel is: 2.6.31-17-generic

So, either you purposely booted to the jaunty kernel at the grub menu,
or your upgrade didn't complete properly. My _guess_ is the latter.

That is because you are still running jaunty:

I think that you should describe how you went about the 'upgrade' & then
we can try to sort it out from there. Also, please provide the exact
Dell Studio XPS model that you have.
