Okay, just to make things clear. Windows Vista does NOT support ac97 audio chipsets.
it DOES support certain hd audio chipsets (the successor to ac97).
That does not necessarily mean that your ac97 audio device WON'T work with Vista, just that if your manufacturer doesn't write drivers, nobody else will.
There are many such things to beware of when upgrading to vista. conflicts between certain hardware configurations, unsupported hardware types (sound cards, video cards etc).
That having been said, once you get it running properly, it's worth the teething troubles.
