Hey Oliver Smith

Currently, web browsers have a limitation that prevents applications from playing audio automatically without user interaction. If browsers allowed this, websites could play audio without our consent, which would be quite disruptive. As a result, we must keep the audio muted by default.

One workaround for this case is to add a "Chapter" step at the beginning of the demo, which would require a button click to proceed. This would automatically play the audio from the next slide.

I hope this helps.
