I'm having an issue inserting multiple video files into a WBT. The original files are in .wmv format. We used the tool in Lectora to convert to a MP4 format because we've found that users on Google Chrome are often missing the plug in to play .wmv. The issue is that the first video we upload and convert works great. Eash subsequent video plays fine, but there is no audio. In total, our WBT will have 13 short videos. We on Lectora Inspire 12.0.2. Thank you for your help!
