Flat line when importing sound

I bought Toon Boom Harmony Premium not long ago however when I try to import a normal WAV. audio file into my animations sound waves are not shown and the sound does not play. I have benn searching around and people say if othe sound runs on quick time it shall work, and it does for me. but still no sound in toon boom.
I would really need someone to help me with this problem since im running late with my project im working with.

I did but then i dont know what to do. I installed it and went back to my toon boom harmony but still no sound

do you installed Quicktime?
you need it. and it’s free.


Hi, yeah I tried that too, did you ever figure out how to fix it?

After installing QuickTime did you restart your computer? That fixes it for some people
