The Core Audio APIs are documented in the Vista Beta 2 SDK.

Frank, thanks for your quick reply. Which SDK has the new set of APIs? Thanks!

The mixer API is now virtualized per-application. This change was part of
Vista's "per application volume" feature. While this does have a negative
affect on some set of applications- indeed probably many of the utility
applications that members of this mailing list create- we feel this helps a
majority of every-day applications work well with the per-app-volume feature.
Applications that truly have a need to access the system-wide volume
controls rather than the application's volume have two options for Vista. These
options can be pursued in parallel. 1) Contact Richard Fricks at Microsoft
(richfr@xxxxxxxxxxxxx) and start a dialog with him to consider adding your
application to a list of applications that Vista will automatically run with
the mixer API in XP-compatibility mode. 2) Prepare a Vista-ready version of
your application that uses a new set of APIs for reading/writing the
system-side volume controls.

Does Vista still support mixer APIs? I have a volume control application
using mixer APIs (such as mixerOpen, mixerGetDevCaps, mixerGetLineControls...).
It works well on 2K/XP. However, on Vista build 5472 the volume I got from
mixerGetControlDetails API is always 65535. Anyone know what's the problem?
Thanks!
Mike
