I have an audio problem. When I publish my Adobe Captivate File, the Audio Files on one of my slides are not playing. Although the play just fine when I used preview. I tried withe different formats such as wav and mp3, but no changes. All other medias in the document such as video files (mp4) are working just fine. The problem is only with the audio files.
