From the Sound Wiki - Sound is a travelling wave which is an oscillation of pressure...

A true vacuum is the total absence of matter in a given space.

Therefore, in a true vacuum, there is no matter in which to produce the pressure differences which lead to the production of a sound wave nor is there a medium for any would-be wave travel.
