NO SOUND

So i have toon boom harmony essentials and when ever I import sound into the project there is no sound play back, it shows the wave forms on the timeline but there is no sound. This is a major problem as I want to do lip syncing. I’m wondering if there is an update or patch for this.
cheers.

Which version of Harmony? Do you have Quicktime installed? Until version 15, Harmony relies on Quicktime for audio support. And bear in mind that if you’re on Windows 10 you need and older version of Quicktime because newer ones do not work. Quicktime 7.7.6 or 7.7.7 should work.
