well, heres something i want to build, but i am unable to find the resources for it. i want to take a connection off of the aud ext connection on a sb live 5.1 card, and then put that into a card that i am gonna build to provide balanced audio signals to my amplifier. does anyone know where i could find some informative pin out diagrams for that?? or of anything like that?

thanx guys, this is the last resort.
