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 t...

Hi Everyone,

I have used javascript code to set volume to 0 (mute audio) and set volume to 0.8 (unmute audio)

the code used is:

$('audio').each(function(){
this.volume=0; //mute audio
});

$('audio').each(function(){
this.volume=0.8; //unmute audio
});

when testing from a web server, this code is working fine in IE11, Firefox but not working in Chrome.

this code is working fine when reviewed locally in IE11, Firefox and Chrome.

Can anyone suggest me a solution for this issue?

Thanks in advance

Hi Ravindra,

Yes I got the solution in another thread, I am posting the solution here too so you can see here.

to mute audio I have used this code and it is working fine:

if (document.location.href.indexOf('html5') < 0) {
} else {

var player = GetPlayer();
Audio.setMasterVolume(0);
$('audio').prop('volume','0');
}

to unmute audio I have used this code and it is working fine:

if (document.location.href.indexOf('html5') < 0) {
} else {

var player = GetPlayer();
Audio.setMasterVolume(0.8);
$('audio').prop('volume','0.8');
}

the condition mentioned above ensures that these commands work only in HTML5 version of the course.

    Hi Anitha
    
    This code is applied to triggers on the audio on/off buttons.
    
    on audio off/mute button, add a new trigger and select execute Javascript and paste the following code:
    
    if (document.location.href.indexOf('html5') < 0) {
    } else {
    
    var player = GetPlayer();
    Audio.setMasterVolume(0);
    $('audio').prop('volume','0');
    }
    
    On audio on button,
    
    add a new trigger and select execute Javascript and paste the following code:
    
    if (document.location.href.indexOf('html5') < 0) {
    } else {
    
    var player = GetPlayer();
    Audio.setMasterVolume(0.8);
    $('audio').prop('volume','0.8');
    }
    
    please note that this code will work only in HTML 5 version of the publish course content.
    
    and for Flash version of the published content you can use the mute toggler as explained in this thread.
    
    give me a shout if you need any more help in Articulate Storyline.
