I recently upgraded (?) my Inspiron 6400 to Win7. Although I now regret doing it, I need to sort it out as I cannot go back to Vista. Is there a Sigmatel audio driver for Win7? Dell does not offer a driver. I visited the manufacturer's site and they do not offer OEM support.
The Vista driver, on the Dell downloads, should work for Win 7. I've upgraded several different PC's, a laptop of my own and several client's PC's and the Vista drivers, including sound, worked for all of these. Win 7 is basically Vista "Improved".
What indication or error are you getting? Have you tried installing the Dell driver?
