Fix sounds issue on an image gallery in Safari (wordpress)

Hi, we’re building a small wordpress website for a video production studio. We installed an ajax gallery plugin with categories (Cube plugin) displaying just thumbnails with audio clips (…not videos): [login to view URL] On desktop, It works fine on Chrome and Firefox but not on Safari. So we have to use previoulsy a trigger to make it work (scroll, button…). For example, on this page which was the previous structure: [login to view URL] On Safari, if you click the play button video firstly, you will got the sound later for each thumbs of the image gallery bellow. If you doesn’t click the play button of the video, you'll got no sound on the gallery bellow. But the client want to separate this video introduction from the Productions gallery images. That’s why, I inserted this video trailer in a specific page. But, maybe we could do it another way. For example, with sticky sections and scroll to anchor to trigger and enable the audio clips. Well, I’m looking for somebody who knows very well all the aspects of videos and sounds displaying on the web actualy. Cause most of browsers now impose big restrictions on this medias (autoplay, sounds…). The ideal would be somebody that got ideas to make works in a UX friendly way. I’m waiting your propositions. Best Chris PS: it will be better if you got real mac devices, and not only Safari on Pc.
