The "tree falling in a forest" question was posed before people knew that sound was caused by vibrations, or even that sound was a physical phenomenon.

I don't think that's correct. The notion that sound is vibrations in air dates back to at least Aristotle. See for example here

I don't know, but Aristotle's writings were not well-known in Europe from the 6th through the end of the 12th centuries. They were re-introduced via the Crusades.
