In any way can sound reflect light or vice verse?

Yes, sound waves change the density (or more generally, refractive index) of the material they're traveling in. Light waves diffract off that varying index of refraction. This is a standard process used in studying materials, called Brillouin scattering, http://en.wikipedia.org/wiki/Brillouin_scattering.
The opposite process, sound bouncing off of light, tends to be too weak to be of much routine use.
