Unfortunately, Apple disables the html <audio> autoplay field. Ultimately a business decision (some context on this here: https://stackoverflow.com/questions/3009888/autoplay-audio-f...).

This is why there is a play button for each track, I'm afraid :( Should that change, I will push an update. That said, autoplay is enabled and works for Desktop web as well as non-ios devices (as far as I'm aware see https://caniuse.com/?search=autoplay).
