Hi Russell,
Just for extra info on this forum. Yes if you are using adapt-contrib-media then you can either change by
1. Autoplay in media.hbs
<audio autoplay src="{{_media.mp3}}" type="audio/mp3" style="width: 100%; height: 100%;"/>
and use
"_media": {
"mp3": "course/en/video/SampleAudio.mp3"
} in component.json. Do 'Display:none' to all other layers.
2. OR you can also add Autoplay to video tag in media.hbs and use below mentioned player options,
"_playerOptions": {
"loop": true,
"clickToPlayPause": true
}
Their are many other options available.
If you need only audio then keep audio controls to 'display: block' and rest all to 'display:none'.
Alternatively if you are specific to audio only then you can use 'adapt-audio' plugin made by Kineo and change their .HBS file with 'autoplay' property their also.
