I like your way of thinking. Don't forget to aticipate any audio processing blocks in between your software and sound card output. There are many processors and filters on the input ADC for example. I don't believe there is much of anything on the output path, but I would check. You will probably want cheap sound cards rather than expensive ones as these will have less " audio fidelity" and more raw DACs.
