You're distorting what I'm saying. You choose the highest sample size
local to the card. If you have a 24b@96kHz file, and your card only
supports playback at 16@44.1, you resample to 16@44.1. If your card
supports 24@96, and you're playing 16@44.1, you don't resample at all,
because it makes no sense. I don't see what's so difficult about this.

I think you misunderstand.
#A bit/sample limited by hardware
If hardware is 24@192, #A is 24@192, unless what you're playing is
lower than that, in which case upconverting makes no sense.
I really don't understand why this isn't obvious. We're all smart
here, why would you think we would suggest something that dumb?
