No one wants to use two sound cards? Speak for yourself. please.
I very much want to use completely separate audio output systems on my PC. I have multiple HDTVs as my monitors, and I would very much like to be able to direct the audio for the app shown on a particular monitor to its own speakers. Audio is transmitted via DisplayPort or HDMI to each monitor.
And if experience has taught me anything, at all, it's that if there's something I want to do with a computer, I'm certainly neither the only one nor the first one.
