I have a GW 5478 with an Intel G33 MoBo. I have been using Vista (using
Ultimate) SP1 for > 2 months with no trouble at all using GW SigmaTel sound
drivers. After the "official SP1" was released I decided to do a clean
install of Vista/Ult and again used the supplied GW SigmaTel sound drivers
with no difficulties. In fact, I have a set of older Creative 5.1 speakers
that I used with my old computer and got these speakers to work with the
supplied drivers also.

I can even go further. I was playing around and did a clean install of XP
Pro (of course I have a mirror image of my Vista Ult) but could get no sound
at all from the SigmaTel drivers....So I went to the Intel site and read
some info on G33 MoBo and I found 3 iterations of that MoBo so I stalled -
just as a guess - another sound driver from SigmaTel for a similar board and
that driver gave me sound (again 5.1).
