Thanks dl65... I read that link and I think its dealing more with a small radio station function... very interesting and I will read up more on it, but I don't think its what I want to do, and plus it looks like an old program.
The name of the program that I'm talking about is VirtualDJ. You can download a copy at thier site, and I highly recommend it for all house parties, it will Beat Mix with an incredible AI-like style that is really amazing! Here is a link to their user manual... hit ctrl-f and punch in "two soundcards" to skip to the appropriate chapter. I know that if you scroll up it says you can run the program on one sound card no prob, but for the true dj, the mix comes with feeling the hardware (ie. the mixboard sound controls) and you just can't achieve a proper mix trying to work it with a mouse, therefore you split the sounds into two channels... I did this for over a year with absolutely no problems so it does work.
Now I want to split my sounds to two different sets of speakers, for two different sets of reasons... I wanna keep my games/computer sounds limited to my computer, and my multimedia to my stereo. The reason for this is that my computer is in the living room, and when I am working on my computer, so as not to disturb others in the house, I listen to my earphones. I have hooked my video card to the tv so I could watch dvds, homemade movies and other stuff on my tv. A lot of DVDs have extra content that you can only access on computer, now I get the best of both. I also host a poker night at my house and I use a program called The Tournament Director, which does wonders for the ease of night. It beeps when blinds go up, but my computer speakers aren't loud enough. Plus the boys like to hear a little rock n roll. Since I used to dj and I ripped all my music to my hard drive, I would like to play that on my stereo. Actually I already do, its just that I have switch cables all the time and thought it would be better to be able to switch via in windows than physically doing it. These are the reasons for wanting to use two sound cards
