Vista is the worst operating system for sound recording. 7 isn't looking much better, it's forcing me to stick with XP.
They re-worked how sound drivers are applied to the system in vista to further help their own DRM system, disabling certain recording abilities, turning off some outputs while some inputs are engaged, that sort of thing, and on top of that put a terrible UI which gives nowhere near the control that you get from the simple sound mixer in XP.
Heck, even though there are a load of really high-end audio samplers that only work with 64 bit vista, I've only ever heard of them being used remotely over network controlled by an XP or a Mac host.
That being said, I don't see why you should have too many issues if you have yourself a small mixing desk with phono out plugging into a sound card or DI box with phono in. As long as the drivers exist, you should be fine.
