I just did the latest update for April for Power Director this morning and have no sound with anything in the Power Director App. Music, clips, nothing has sound. Everything is muted. I have checked security settings in Mac, I have deleted the Power Director App and downloaded it again. I have messed with everything possible and still have no sound. I'm dead in the water for making videos until this gets fixed. I would like to go back to previous version, but can't even do that.
