Vista Audio Stack and API

Charles recently caught up with seasoned Niner, Larry Osterman, an SDE and 20 year Microsoft veteran, and Elliot H Omiya, a Software Architect and audio guru, to dig into the innerworkings of Vista's updated Audio Stack and new user mode API. Much of the guts of Windows audio have been moved up into the land of the user and this has consequences for both Windows audio developers at the API level and for Windows at the general programmability, reliability and stability levels. Great stuff.

Enjoy

MF is a com-ish API, but you don't activate objects with CoCreateInstance.

WOOH! WOOH!
I'm just curious about how you provide per-app volume control for "legacy" apps that don't talk directly to the WASAPI. Do you create a session for an app on the first request for sound service? How do you differentiate between 2 instances of the same .EXE?

BTW, it's a bit funny that a video about audio has such a low audio level.

is there an ability in vista to set on which speaker you hear an application? for example i want the media player on the 2 front speakers and the game on the 2 back speakers? if it's possible, is there also a possibility to set the volume for each application on a per speaker base?
