Sigmatel drivers for Inspiron 9400

Hi all,
I've searched the forum and got references to but can't find actual posts re: installing drivers for this.
Dell Inspiron 9400 laptop, dual boot of XP Home and Windows 7, install of public beta went really well. In Win7 I have a volume icon in task bar, but no audio output I can hear... Win7 is using the digital output with spidf, which I can't use, it shows no other option. I can't seem to install the original drivers (from Dell, for XP), they fail (sez they're not the right drivers for my hardware, even though I tried installing as Administrator).
In XP, device manager reports the SigmaTel High Definition Audio CODEC, what am I missing here? I think I'm needing to install the "legacy audio" drivers??!!
Any help?
Thanks

Duh... I looked at some more posts, and all I had to do was install the Vista driver for the sound card. I ran it as Administrator, and it's working fine.

Anyway, maybe this post will help some other twit like myself.

Have a nice day.
