Website sound not playing on emailed link

Ojustaboo

Hi got sent an email with this link in

https://www.native-instruments.com/en/products/komplete/keyboards/kontrol-s49-s61-s88/?

If I go there, first of all I get a black box that I have to press the x to get rid of, then none of the sound examples play anything, only got the problem on that page, rest of your site seems fine.

Tried it in Safari and Chrome on IPad and also tried it in Safari on my iPhone

here’s a pic of black box

And if I click on any of the audio links such as the “Hear polyphonic aftertouch in action” in the below link, I hear nothing, the video plays fine, just no sound.
