Answer 1

I've tested this and it works.

HTML

<input type="range" id="volume-control">

JS

let audio = new Audio("http://21273.live.streamtheworld.com/LOS40_DANCE.mp3");

let volume = document.querySelector("#volume-control");
volume.addEventListener("change", function(e) {
audio.volume = e.currentTarget.value / 100;
})

I hope it helps

You can either use an input range and I think control the volume with js or use the native controls

So why not just use an <audio> element on the html? you can give the attribute controls and then you won't even need $("#play-pause-button")

<audio src="your_src" controls="true">

Or is it due to styling? If so then here's an alternative:

<input id="volume-control" type="range" min="0" max="100" value="50">

const audio = new Audio("http://21273.live.streamtheworld.com/LOS40_DANCE.mp3");
const configure = $("#play-pause-button");
const range = $("#volume-control");
configure.on("click", function () {
    const hasPlayClass = configure.hasClass("fa-play");

    //in nativejs its .classList.toggle() idk about jquery but here's my guess
    configure.toggleClass("fa-play");
    configure.toggleClass("fa-pause");

    audio.muted = hasPlayClass;

    if (hasPlayClass) {
        //did you mean audio.autoplay? Used to be autoplay
        audio.autoplay = true;
        audio.play();
    } else {
        audio.pause();
    }
});

range.on("change", () => {
  audio.volume = range.value;
});

audio.on("ended", function () {
    configure.removeClass('fa-pause');
    configure.addClass('fa-play');
});

Last option: use a library for audio controls.

On a different note this code was very bad and repetitive, would recommend not using jquery any further since it barely shortened the code here
