There is a crew meeting tonight, and because we're at a new venue this year I'd like to check in before I answer. I want to make sure you get accurate information.
I will say that typically each room will have a projector, a screen and an audio setup, and that you shouldn't need anything more than a laptop and a dongle (the adaptor between your laptop and the projector if you are a Mac user).
I will post audio specs on this thread later tonight. I will also post general tech specs (including audio) on a new thread.
