Stop autoplay on an audio

Hello,
I have an audio field for which I use the link module.
I enter the URL of the audio and in the manage display tab I chose as format options: iframe.
Normally it works fine, with archive.org, ivoox, etc, but with some audios I can't manage to avoid the autoplay.
this is the audio in question.

can anybody help?
