Vostro 1500 and Vista Audio Capture

I have a Dell Vostro 1500 notebook with Vista Home Premium on it. Currenty I
am running Roxio Ver.9. The audio capture only detects the on board mic (has
a mic/cam combo on the lid). XP is different. I had it loaded on the
notebook at one time and it would capture different audio instead of just
the mic. Does anyone know if Roxio Ver.10 has fixed this? Or is this unique
to Vista?

Thanks,
Greg
