I have been using VideoPad for a little more than a year with no troubles. I really like this program. In the middle of splitting a large file into smaller segments, all of a sudden, the audio went silent. I have tried so many things! Delete the segment and start over. Close the program and reload the original file. Uninstall and reinstall the program! Start a new project and use a different video. No matter what I do I can't figure out why the audio went silent. I still have sound for all my other apps.
