As the temperature goes up the speed of sound goes up since molecules are already moving faster.

More commonly the term refers to the speed of sound in air. The speed varies depending on atmospheric conditions; the most important factor is the temperature. The humidity has very little effect on the speed of sound, while the static sound pressure (air pressure) has none. Sound travels slower with an increased altitude (elevation if you are on solid earth), primarily as a result of temperature and humidity changes. An approximate speed (in metres per second) can be calculated from:
where (theta) is the temperature in degrees Celsius

Well I've just learned something tonight, which is that an increase in temperature increases the speed of sound. And that for an ideal gas, pressure does not affect it.
Take a look at:

"Sound usually travels more slowly with greater altitude, due to reduced temperature"

In gases, the speed of sound is proportional to the square root of velocity:
a ~ âT
where a is the speed of sound and T is the temperature of the gas.

When it's hot out, no one knows about your gas problem until after you left the room.

colder the slower it would be and vice versa
