i am using virtual audio device/driver get from DDK.

In DDK have available virtual audio driver, i have build msvad folder then
install with msvad.inf file. Chose AC3 in during installation.

I would like to pass sound data (were captured in to a sound buffer) to
virtual audio device. And sure my Audio In device is a real device.
But it seem , i can not use this virtual driver for now. I must change code
in source files of MSVAD and rebuild and then reinstall, right?

Can help/show me how to pass the sound buffer to virtual audio driver, and
then get this buffer from virtual audio driver to real audio device for
playback..

This is need for me, hope will have anyone can help me..

Thanks for any help.
