An interesting tangent: sound can be recovered from visual information too:

Considerable amounts of money and expertise have been thrown at sound analysis, and it's used in a range of situations from telling what submarine is in your waters to knowing what a typist is typing.
And eventually people put parallel ports on typewriters because typists are more expensive than a parallel port, at which point you've got a cumbersome but very hackable printer.
