Hey, hi again. The wix audioplayer is supported by API as you may see here https://www.wix.com/corvid/reference/$w.AudioPlayer.html
You do need a playbutton, just need to load from the dataset the url.
Now, when I add the audioplayer on the page and connect to an mp3 file directly from the library (not the dataset) it loads and plays.
When it is in the repeater and connected to the dataset it does not load (while it used to load and play) and while other repeater items (images, text) are loaded ok.
