I have no idea. But here's an alternative.
You can insert a little white play/pause button into your thread that plays audio from any YouTube video you want when a reader clicks it, and stops when it's clicked again.
Here's a thread where I did this, so you can see what the end result is like.
And here's how to do it yourself:
Paste the following into your thread towards the beginning, before the story starts. (Or wherever you want your play/pause button to be.)
{div= width:100px; height: 22px; margin: auto; overflow: hidden]{div= width:100px; height: 22px; color: white;]{fa]fa-play{/fa] {fa]fa-pause[/fa][/div}[/div}{div= width:100px; height: 22px; margin: auto; overflow: hidden}
{div= width: 190px; height: 22px; margin: auto; opacity: 0%; margin-top: -100px; padding-left: 32px; ]{media=youtube}#####[/media]
{div= width:100px; height: 22px; margin: auto; overflow: hidden]
Now, pull up a youtube video in a new tab with the audio you'd like to insert. Where the 5 underlined yellow pound signs (hashtags) are?
Delete those, and paste in everything in the youtube video's URL that comes after this-> /watch?v=
Everything after the equals sign goes where the red hashtags are, but this won't work if the video is part of a playlist. Just find it and play it on its own to get the right video ID.
And finally, in order to make the code actually display, I had to replace a few Brackets [ ] with these fancy parentheses
{ } colored red so you can find them all and change them back to normal brackets.
I really hope this helps, I'm not a perfect teacher (at all) but I think I covered every step. Have a great day.
