Captcha autoplays audio when the page loads. Is there anyway to stop this? We'd like the audio to only play when they click the link..
You can see/hear the behavior here:

Hi Paul,
By design the RadCaptcha will try playing the audio code using <audio/> html5 element. Since not all browsers support <audio/> tag, as a backup variant the code is played using the <embed/> tag, which requires the browser to install QuickTime plug-in. So, in case the plug-in is configured to play the media file immediately after the page is loaded, the audio code will be played immediately.
To avoid this try setting autoplay attribute of the <embed/> tag to false, as shown in the following code:
All the best,
