If you look here Dell XPS 410 Audio Drivers you can see that the only two options for your model are 4 Creative labs versions and 1 Sigma Tel. The one Sigma Tel version must be yours as that is what audio you have. You also must have the driver that it was shipped with which is A07 from 10/5/2006.
A simple matter of deduction my dear Watson (insert Sherlock Holmes Smilie )
