hi, i am a newbie to Device drivers. i want some sugesstions
i have two sound cards installed in my system. say  card A and card B.
i want when any audio is played on card B it is also played on card A as

an idea in my mind is that i should write an upper filter driver for card B
that will generate duplicate requests for Card A and will pass actual
requests to lower driver for further processing. is it possible or not? and
if it is how can i genrerate similar requests for sound card A. recommend me
some references abut APIs that could help me to acieve this.

Any suggestion for doing this  in some else way.
