Hi all, I am developing the virtual audio driver based on MSVAD sample. My requirement is capture the audio and pass to user mode application (lets X) .This X application pass the audio to remote application on different machine. If I change the volume level on main PC it should not affect on remote machine. I made the VAD as my default audio device to capture the audio and pass to X application (using Copyto &Copyfrom in MSVAD).Everything is working fine on XP. But the problem is on vista PC if I change the volume level it has affecting the volume on remote machine. Any tip or hint (or pointer to an article) would be greatly appreciated. Thanks in advance pasya
