my guess is that it is not as simple as you might think. Having 3 audio cards on one computer might create conflicts. Of course playing 3 songs at the same time is certainly doable but separate them to different ports maybe another story though.
I have pre-wired my house for distributed audio and getting ready to buy the hardware so that I can distribute 4 audio sources to each room of the house.
What I want to do with my PC is to store my audio files on it and then be able to stream up to 3 songs at once (1 each to three rooms).
Do I need three sound cards to pull this off? I have an Athalon 64 3000 processor and 1 GB PC3200 ram. 5.1 sound is built in.
Additionally, is it possible to have 2 or 3 Windows Media Players running at once? If I had three different media players, could each be set to only play through one specific sound card?
