sound card fails with vista

on my old XP machine i had an sound blaster audigy se sound card and i
the mediasource 5 player it had an option called "what you hear" i use
this option to stream audio clips to friends combined with manycam i us
to broadcast my screen and audio while gaming to my friends

i took the card out of my xp machine and put in this vista home basic 3
bit machine and i cant get what you hear option back to save my life
ive been searching for about 4 hours with no help. all i run across i
other forums and people suggesting sound recording software that record
through the spekers. this is not what i am wanting to do i dont need t
record anything, i need to broadcast the sound thats coming through m
speakers bypassing the mic

as i said i am needing the "what you hear" option to broadcast m
gameplay via msn/blogtv

any idea how i can get the "what you hear" option back

i dont really want to go back to XP but i will if its the only way i ca
get the option back
