Do the video clips not also come with audio played with video on site?

I bought the Broadcast News package and newspaper open package and they don't appear to have the sound file that was played when I previewed the clip.

No idea what "packages" these are. Are they individual clips?
In any case, if the preview has audio the purchased file should also have audio. Contact P5 directly for help.

Guessing this is related to After Effects Project - if so then you need to purchase your own sound effects and music to insert into the project.
