You can look in my guide, there are two sections that may help you. Digital Output and Multiple Sound Cards. Lucky for you they are one right after the other (be sure to read the links, they have important information you should know):

the guide didn't help. all the links in the guide describe how to use the SPDIF or IEC958 of the sound card's mixer but i have none of them.
the only thing i have is PCM and tht's it even though it supports SPDIF and in win XP it works.
is there a way to send AC3 as PCM? it is a trick i use in XP to make it work...
