Is it possible to MUTE audio in Storyline? I'm working on a course with a ground-up custom interface with a button that's supposed to mute/unmute - not pause/play or stop/play - the audio. Are there any Javascript gurus out there who know if this is possible? And if so, can you provide the scripts for mute and unmute? That would SO make my day. Dazed and confused... Patrice

Awesome! You have no idea how much I've tried to get this feature to work. Thanks for posting!

A life saver code. var appState = require("helpers/appState");appState.onToggleVolume();//mute Thanks to whoever came up with this solution.

This has been working for me. Add to a javascript trigger: DS.appState.onToggleVolume();

It's likely possible in the HTML5 version to trigger audio level changes via JavaScript. Currently, in the Flash-based output, volume is controlled through the compiled player and we don't have access to any exposed functions for controlling volume / mute other than the volume control in the built-in navigation bar. It may be possible to embed a Flash file that would provide global volume control but it wouldn't be linked to the built-in control and I'm not completely sure how reliable it would be. The problem isn't a JavaScript problem It's a Storyline player issue. It may be possible to workaround it. I'll grab 15 minutes this afternoon and build / test one. If it works, I'll post the file and instructions for use.

Hi Anitha, Apologies for a late reply, I had been bit busy. Yes, you need to implement 2 different approaches to control the audio in Flash and HTML5. HTML5 - coding I have explained above. Flash - Please read this thread completely and Implement the solution provided by Steve, it works perfectly for Flash version. These both have to be applied together, mute toggler will work only in Flash version and the HTML5 code will work in HTML5 only. Let me know if still you need any more help. Regards, Ajay Khatri

Hi,

I just observed that this flash-javaScript workaround doesn't work on Firefox or Chrome. It only works on IE. I downloaded the muteToggler attachment from this thread and published it and noticed that it only works on IE. Following are the details.

Storyline version used to publish:Update 3: 1305.2012

IE 8 + Flash Player 11.8.800.94 (works fine)

FF v23.0.1 + Flash Player 11.8.800.97 (doesn't work)

Chrome v29.0.1547.66 + Flash Player 11.8.800.97 (doesn't work)

Has anybody experienced same issue?

Thanks in advance

Hey MK - are you running these locally or from a remote host? Sounds like the Flash Player Security Sandbox could be playing its hand.

You can use a trigger to execute this javascript code on HTML5 mode,

$('audio').each(function(){

this.pause();

});

This will pause all the audio which are active. You can execute this on conditional basis (say when timeline starts if variable audio = false) then call this code otherwise let the audio to play by default.

By the way, i have accidentally pressed the suggested answer button on your reply. Could not find a way to undo it. Sorry about that!

OK, my friends. Here's a quick example and widget that will let you mute all audio. Note that this won't work in Preview or in HTML5 or iOS publish. It's Flash based and requires that you publish. If it doesn't work locally you may also need to add your publish folder to the Flash player security settings.

This does use JavaScript as an intermediary so that Flash can pick up variable change conditions from Storyline. Pretty straight forward. Let me know if you have any problems.

Hello,

Is it possible to add the Javascript HTML5 mute toogle into this sample file as well?

Much appreciated

Hi Julie,

You may want to send Steve a private message if you need additional help with it as I'm not certain he is subscribed, but he did note that it won't work within HTML5.
