Just make it a bit louder, before summing it into the left and right channel

Right... so why isn't that done already from the 5.1 signal?

Because other times when it's not dialogue (or even when it is--the busy/crowded street effect) you may not want the center channel gain to be raised during mixdown.

Consumer hardware can only guess. A sound engineer can know.

I have no idea why that’s not being automatically done when the mixdown occurs in the player.
