Hi All,

I have a project creating a synthesiser with a step sequencer which works perfectly in Chrome and Firefox - In Safari however there is no sound at all. All the functionality seems to be working just no sound… I have the latest version of P5 sound and cannot find any thing on here that can explain… there are no errors in the console so i have no idea where to start debugging.

Hello, and welcome @bedlamagogo!

I think you’ve stumbled upon the user-must-interact-before-sound-can-be-played-feature. 😊

> Hello @calfish, Some browsers, like Safari on iOS, won’t play audio unless the user interacts with the page first, like tapping a button. To successfully play audio in those browsers, you could add a “Press to play” button and start playing audio after the user tapped it. From [Apple’s Safari HTML5 Audio and Video Guide](https://developer.apple.com/library/archive/documentation/AudioVideo/Conceptual/Using_HTML5_Audio_Video/PlayingandSynthesizingSounds/PlayingandSynthesizingSounds.html#//apple_ref/doc/uid/TP40009523-CH6-SW1): Note: On iOS, the Web Audio API requires sounds to be triggered from an explicit user action, such as a tap.

Thanks for the welcome Sven 🙂

I might be missing something as not sure what you mean by user must interact - there is a button called start/stop which calls a method to begin - would this be what you mean by user must interact

Yep, a start/stop button is the solution. But your sketch is trying to do something with audio before the user has interacted (pushed that button). I get the following warning in Chrome’s JavaScript console when running your sketch:

The easiest solution is to use `userStartAudio()` – theres an [example in the p5.js Reference](https://p5js.org/reference/#/p5/userStartAudio).

Thanks so much for that it certainly helped with safari - I have some other issues in chrome to debug but that was a great help
