Re: Vista Master and Wave Out volumes - Same?

When running Vista natively (not in XP Compatibility mode) my Realtek exposes
separate Master Out and Wave Out controls, but they are apparently really the
same exact control as far as the kMixer goes. If I move the Vista Volume Mixer
slider for my app, both Master and Wave track together. If I move one or the
other alone in my app, it *appears* to be a separate control... but as soon as I
touch the other, it snaps to the same relative position.

Can anyone confirm or deny if this is always the case under Vista? If it is,
then I will disable Wave Out to make it less confusing to the user.

I believe that is the case if you are using the old mixerXXX API. The Wave
Out and Master Out are virtualized to the app, you're not touching the real
controls.
