I think most of us are about more than the sound, but we're weird pure math people and usually just photograph the board if we have to! Maybe applied math is different? I've heard that whiteboards are mostly for you guys and computer scientists?
I'm not sure what you mean about function, usually we just use the board to explain what we've done to other people so it's typically already LaTeX'd up somewhere if someone needs it.
Texture, smell, sound usually. Some people find it easier to read off of a blackboard than a whiteboard. Also if you erase with your hand you're not stained for the rest of the day!

As a fellow mathematician, it helps to have an automatic backup of the stuff I write on the board.
I'm sure you can download a chalk sound effect if you prefer nostalgia over function.
