spec sheet for that sound chip it would explain what those were.

I agree that the names are highly non-intuitive. for example on most cards,
the input volume controls, like say the line in volume control, does not
affect the volume of the signal delivered to the computer. It controls the
volume that is delivered by the input to the output channel on the sound
card.

As I said, I think by reading the spec sheet for the sound card chip.
