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 well
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.
