Could aliens naturally evolve synesthesia?

For all who are unaware, synesthesia is a condition in the brain where two or more senses are connected; for example being able to see sound or hear color. Of course they do not actually see color or hear sound, but their brain connects their sense, so they attribute certain sense to other senses.

Is it possible for evolution to favor this condition and if so, is it possible for it to become not a condition, but a feature?
