Background music muted until first mouseclick

Problem: I set a music file as background to play across all slides. It is set to autoplay and loop. The problem is that in Preview and on the final exported project, the music is muted and does not unmute until I click the first mouseclick area.The sound doesn’t start at the beginning of the song, but later in the song as if it had been playing from the beginning of the project but was simply muted.

ActivePresenter version: 8.1.1

OS: Windows 10



It’s not possible to unmute the audio without clicking due to the autoplay policy on most browsers.

The best practice to overcome this issue is inserting a button on the first slide. The user must click on that button to start the course.

You can clear the Disable [Click or Tap to Unmute] Notification check box on Export to HTML5 dialog to remove the message on the top-right corner of the browser.


Thank you very much for the quick answer!
