Camtasia (Windows): Audio Glitches, Does Not Play Correct Section or is out of sync

Problem

When playing back the video in the timeline, the audio glitches, skips, does not play the correct section or is out of sync.

Solution

This is fixed Camtasia 2019.0.8 and later 

This is a known issue with certain MP3 files. We most often see it with variable bitrate MP3 files. The best workaround is to upload the media file to Audacity, a free audio and recording editor, and export it as a WAV file. Then, use the new file in Camtasia.
