virtual audio driver development

3 New Member
Hi,
I am trying to tap the audio data which is going to play by the player. So i tried to use the virtual audio driver (simple) which is msvad path of WDK. I have couple of questions. Can anyone in this forum help me out?

1.do we have any IDE for building and debugging the kernel mode drivers for windows XP?(like visual studio for any appln)

2.What i have to implement in the copyto or copyfrom functions in the wavecyclic file? and where i have to call these functions to get the data which is going to be played?

3.do you know from where the pcm data is getting played in the audio device?

can anyone give me some light on this issues?

Thanks

I think somthing like Ddkbuild will be what you are looking for.

After installation of my msvad simple driver, when I try to play some audio files using any player I am not getting the debug traces (DBGprintf) from the copyto
function.
So which means that our copyto function is not getting
called during play back.
Any idea on this behavior of simple msvad driver?
