如何让我的音频在 socket.io 中播放？

Question

I am making a couple updates to my socket.io chat and I am trying to get audio every time a message is passed through. When I send the message I get Uncaught (in promise) DOMException Here is the code that gets run when a message is passed through:

socket.on('new message', (data) => {
            var messageE = document.createElement('div')
            messageE.classList.add("well");
            messageE.classList.add("msg");
            messageE.innerHTML = '<strong>'+ data.user +'</strong>: ' + data.msg;
            console.log(messageE)

            chat.appendChild(messageE)
            audio.play()
          })

I may wont be able to respond till late afternoon.

A few seconds ago i got the same error but i fixed it. It is not the coolest solution but it works. What i did telling the browser itself to play the audio and not directly from a socket.

Make a outside Variable(example socketCheck) that is on false . That will become true when the socket is called. The if will continue when it is on true on false it wont. When the sound got played turn the soundCheck on false again Here is a example;

var soundCheck = false;

socket.on('new message', function(){
    soundCheck = true;
});

if (soundCheck) {
    sound.play();
    sound = false;
}
