The Bards technically do. The song has Alduin's name in it, and they start singing it once you beat Alduin. What's more, they dedicate it to you for what you did. And the guards are obviously referring to Alduin, as they only say it once you've killed him. You can kill all the Dragons you want and they don't say it, but it's your final defeat of Alduin that triggers it. Therefore, they're aware of what happened and therefore of Alduin.
