I'm always happy to discuss sound cards with mixers, though! As a supporter of the Bloop Museum[1], I think that the "What might have been" if we had dedicated hardware for playing dozens or hundreds of sound files at a time is an interesting question. There's a lot of experimentation in the audio space that has kind of died out, because audio is so cheap - While over in in graphics, we're still seeing interesting advancements and dead ends.
