I'm not sure if it's related at all, but a bug I've noticed with Vista and Server 2008 causes apps that use sound not to register as using sound. This means that when you click the little speaker icon in the system tray that brings up the audio mixer, the newly loaded app doesn't appear in it, and no sound comes out of it. Restart the app and it usually works, though.

Systme-wide loss of audio happens to me as well, and it seems to be caused by Vista randomly mis-routing audio output. Off the top of my head, if you right-click the speaker icon, one of the menu options takes you to the Output Device menu. You might see SPDIF enabled and speakers disabled, as I sometimes do.

And, yeah - as my man Jay says, it's all down to the new way in which Vista 'empowers' the user by completely changing the audio subsystem. To be fair, it's not all bad - it makes it possible to individually set app's volume levels and do all sorts of fun things with outputs - but it cancause no end of bother.

Focusrite saffire and I'm using its ASIO driver.
