FM provides a better scheme as compared to AM as far as performance is concerned (especially in non-linear channels).
the video signal needs very high bandwidth to cover minute details which would turn to be impracticable to be commercialized. therefore AM is used for video part.
the bandwidth needed for sound signals is much much lesser than its video part so FM is affordable for sound signals.
therefore FM is used for sound signals.
