Light and sound do not travel at the same speed, the speed of sound can not be hindered by light. Example if a plain flys over your head a 2500 feet at the speed of sound it's day light still, you hear the boom about 4 sec after it passes, this would not change at night, you at night the sound will echo or care farther do to dead silence and no other sound waves intercept it. Think of it like dropping a stone in the water the ripple effect cares till it hits something then dampens. So to answer your Question there is no difference between light and dark when it comes to sound, just perception.

Sound speed is related to the density of the medium its traveling in. Of course temperature affects density as well. In the day time the sun affect densities of material by heating them up.
At night the material is denser but not by that much. Theoretically sound should travel faster however the difference is so small that we can say they are the same.
It is true that a night sound carries a long distance that is because there is no other activity taking place so stepping on a twig at night can be heard at a distance.But the sound does not travel much faster at all.

Did i just see the idea of light and sound crashing :|. Oh my days. Anyway, since your just asking about dark and light, iam not going to talk about daytime and nightime, dark doesn't necessarily mean nightime on Earth neither does light mean daytime on Earth. We can just fink of a closed system with no other factors affecting it (such as humidity, background noise, dis and dat as others have suggested) other than one system being illuminated by a bright white light and the other being completely dark. The result will be that as longs as light is the only difference in the two systems the speed of sound in both of them will be completely the same, no difference in both systems (light and dark). If your talking about nightime and daytime on Earth subject to loads of different factors such as wind, humidity, background noise etc etc. then there are too many factors to take into account to tell exactly if it faster or slower.

the amount of light does not change the speed of sound. However, the effects it brings about does. Sound travels faster the more dense the thing its traveling thru, but the more dense, the quicker it will die out. So when theyr is a thick fog, or its humid, thtll change the speed

There is less to hinder the travel of sound through the dark, as lights energy & MAGNETISM, along with anything moving, will disturb / affect sounds perfomance,thats why speakers have powerfull & sometimes huge magnets, & the dark ( pitch black) isn't energy related, so it will have maximum perfomance, "bar any obstacles"; Although sound travels at one speed, any energy or obstacles will cause sound to fade.. Also, say with at night time, the chances are there is more moisture for the sound to travel through. Also sound is louder at night, fact! so dark it is.

No difference. The speed of sound is nearly equal to the average speed of the molecules of the substance through which it is traveling (differs by a small geometric factor), which is in turn proportional to the square root of the absolute temperature and inversely proportional to the mass of the molecules. A little calculation reveals that the speed of sound is nearly three times as fast in helium as it is in air, which explains why inhaling helium gives you a Donald Duck voice: the resonant frequencies of the cavities in the vocal system are raised because of the increased speed of sound. (There is no effect on the vocal cords.)

Guessing, through the night air. There is usually more moisture in the air at night, and sound travels through water faster.

sound only travels through air and is not influenced by light and that's why you cannot hear in a vaccum

It makes no difference.

think and use your mind its a constant flow until something get in front of of it as for dark or light its bollocks its a constant flow .? i will go to bed and think about this because i am now thinking of other possibilities
