According to de Broglie hypothesis, light has dual nature i.e. particle and wave.
And sound needs medium to travel . So can we say that, sound could travel through light as light has particle nature?

This is an interesting question, and the answer turns out to be yes. Ordinarily we say that photons do not interact with one another (that is, they pass right through one another without colliding), but this is only an approximation. Photons interact (very) weakly at all energies, and this ability to scatter means that a gas of photons can indeed support acoustic waves, which could in principle be observable for extremely high energy densities or extremely large distance scales.
This paper (also on the arxiv) derives corrections to thermodynamical expressions for a photon gas due to this photon-photon scattering, and demonstrates that the speed of sound in a photon gas would be exactly equal to $v_s = c/\sqrt 3$ (which is, incidentally, the speed of sound in an ideal ultra-relativistic fluid). This paper derives the same result in a less technical way.
