Hello.

I have task - catch all system sound, process it, and put to the output.
For Vista it is implemented via sAPOs.

But how to do it for Windows XP?
Using GFX allow process output only for USB devices, but i need support for
all of them.
Also, I dont want to replace installed audio driver.

If it possible in correct way in XP? And how(in some words) it can be
implemented?
(The best case - adding my filter driver after KMixer driver).

I just need some professional advices before development XP version.

Thanks for help.
