I just updated to powerdirector 20 from 14, and right when I entered one of my projects, i noticed that the audio was so loud It was going to make my ears bleed. I started a new project and the audio was fine. After a bit of messing around to find out the issue, i noticed that whenever I added Reverb (Not in audiodirector, just in the default audio editor) it would increase the gain very high, to where it sounded like a jet engine taking off, yet you could still know that i was saying words.
After trying to reinstall it, update drivers, and everything I could think of, It still has this issue. So a lot of my projects I've been working on that have reverb are broken for now until this issue can be resolved.
