You can't apply a soundcard mixer gain change at some exact point in a sample stream. So you can't change the master gain and change your internal scaling to compensate at exactly the same time. There will always be a glitch.
That's the important point. And because look ahead for a realtime livestream is impossible without a time machine, you need to lower the level with a guess about the needed headroom, before you increase the other level, assumed we are near at margin of full scale.
Or is it possible for software to be that fast, that it doesn't matter? Perhaps a look ahead is possible?
