The speed of light is just the speed of any particle without matter. We just use "speed of light" since its simpler to understand and talk about rather than saying "speed of matter-less particles".
The speed of sound is the speed of air-molecules bouncing into each other (~300m/s). Since air-molecules have matter, they dont travel at the speed of light.
