Well yes, but why is that exactly? I find it pretty fascinating that all sound travels at the exact same speed. You'd think that it had some fluctuation in it, causing one wave to exceed a slower one. Yet it runs along consistently like a fluid vibrating highway.
I will bring criticism down on my head again for this, but if it were not so then the universe would be unworkable. If the speed of sound were variable, then one day you would hear the train coming and get out of the way, but the next would be lying in pieces on the tracks before you heard it. Since sound predates life, it is very convenient that its properties are so convenient for living creatures. Before life sound was totally redundant, so why did it exist? Inanimate objects do not need to hear anything.
The same applies to the speed of light. In today's universe it needs to travel so quickly for the universe to be workable. Yet a couple of seconds after the Big Bang, its speed was the same, yet unnecessarily so given the size of the universe at that moment. Did light intuitively know that in billions of years' time it would need to travel so fast (?) That means it intuitively knew that the universe would keep expanding. However, light does not have consciousness. So, once again, how does science explain the fact that it worked out so conveniently?
