What are the effects of weightlessness on sound waves, if any?

No considerable effect, I would guess. In a room here on Earth, you can neglect the effect of gravity on atoms and molecules in the air, since the kinetic energy of the particles is so large. On a larger scale, gravity will lead to a pressure gradient and that will affect a soundwave, but not the mechanism of the propagating sound wave.
