I don't buy this, at least not without further explanation. One needs a system of units to measure the speed of light (unlike dimensionless mixing angles and mass *ratios*). Unless one finds a system of units that is as "natural" as that in which hbar, c, and G are equal to 1, one might as well simply say that the speed of light is 1. Of course it could be possible that a TOE could explain the ratio of the speed of light to the speed of sound in air at room temperature and pressure. Whether you want to call this "explaining the speed of light" or "explaining the speed of sound" is a matter of taste, but since sound is a much more complicated phenomenon than light, I would call it "explaining the speed of sound".
