"The thing is, hardware mixing is a thing of the past, modern soundcards
don't do it anymore. Precisely for doing things like mixing in software
SIMD CPU extensions like SSE have been invented. Modern sound cards
these days are kind of "dumbed" down, high-quality DACs. They don't do
mixing anymore, many modern chips don't even do volume control anymore."
