Mobile Extension - sounds


Is it possible to play sound effects on mobile twitch extension? I can play audio on overlay twitch extension it works fine, but when I play it on mobile it does nothing. I am using HTML Audio.

Worked fine last I was testing this on mobile.

However it will pause the stream if a stream is playing.

All extensions require a a volume control to be present
And the volume to start at muted/0

So you’ll need a volumne control.

I was invoking on a “positive action” from the user.
IE A button press.

And invoking via something like:

        cheersboard_preview = new Audio();
        cheersboard_preview.volume = parseInt(document.getElementById('cheersboard_preview_volume_control').value) / 100;
        cheersboard_preview.src = SOMEAUDIOFILE;

        var playPromise =;
        if (playPromise !== undefined) {
            playPromise.then(_ => {
            .catch(error => {
                console.log('Play Error', (error.message ? error.message : error));
        } else {
            console.log('Somethings awry');

cheersboard_preview_volume_control is a HTML input of type range

You will probably want to spit out the error’s to a HTML Text area or something to see whats going on

I get this error:
the request is not allowed by the user agent or the platform in the current context, possibly the user denied permission.

the volume is 0 at the beginning and I am only setting it to 0.5 if user enables sound on the extension.

First google hit:

Sounds like the user didn’t interact with the webpage first, “sufficently” for the browser to allow audio playing.

This isn’t an extensions problem. But a general web problem.

For localtest you are also battling user interaction score, and/or the possible lack of SSL on your localtest.
