There is no attenuation due to absorption, but attenuation will occur due to divergence (spreading out) of the wave.

when a wave travel through medium then sound is produced
Yes.
A direct wave is a radio wave that travels directly through space without getting refracted by the ionosphere. In other words, it travels straight to the receiving antenna without being refracted.

Light travels as light energy. Light is a type of electromagnetic wave.

light travels as a transverse wave and it can travel without any medium as it does while travelling in space.
Yes, sound travels through space when the space is filled with some medium such as air (or water or iron or cetera). Sound is vibrations in the medium which travel as a wave. If there is nothing in the medium, no sound travels through it. Outerspace is pretty empty. You won't hear anything if you're in outerspace (except sounds from inside your space suit/ship). P.S. Do you mean the sound of a wave (like splashing on rocks) or a sound wave?
