URGENT! Sound won't work

Whenever I import a .wav file into a scene in Harmony Premium 14.0, it just doesn’t play at all, even when I press the audio logo and press play. The waveline is flat all the way in the timeline and the Xsheet when there’s supposed to be something hearable all the way. The audioclip is 1 minute 26 seconds - long. I installed quicktime 7.7.9, desinstalled then reinstalled toon boom harmony, but nothing works.

I’d like some help as soon as possible because I’m working on a contract right now and I need the sound for timing and lip-sync. Please help me, I’m desesperate!

In the “Play” menu - make sure that “Enable Sound” is checked.
If it still doesn’t work contact support and send the audio file for analysis.
