Classic sound mixer

Good day, everyone!

I write a sound mixer and I need getting under sound device capabilities control such as I can got with windows mixer. I can manipulate general volume and mute states of mixer, but I can't gain an access to other options, for example: my system has Realtek HD Audio mixer and it makes following controls:

• synthesizer: volume, mute and balance control;
• front: volume, mute and balance control;
• rear: volume, mute and balance control;
• subwoofer: volume, mute and balance control; and so on.

My OS is Windows XP, so I use a standard mmsystem library. it takes me to find all sound devices and to get a list controls that i can got. But list has only volume and mute controls.

Wh开发者_JAVA技巧at do I want to come at capabilities of sound mixer?

what functions did you use to list your output ? did you use only the wave* set of function ?

have you tried the mixer API ? the documentation for those functions is here, and more informations may be found here.
