'Implement sound in sweetalert popup

English is not my mother tongue, please excuse any errors on my part.

Is it possible to implement an audio file in swalfire popup. I would have an notification/sound during this popup:

Swal.fire({
  title: 'Custom width, padding, background.',
  width: 600,
  padding: '3em',
  background: '#fff url(/images/trees.png)',
  backdrop: `
    rgba(0,0,123,0.4)
    url("/images/nyan-cat.gif")
    left top
    no-repeat
  `
})

This worked for me

var soundfile = "sounds/RedAlert.mp3";
Swal.fire({
                title: 'Your Title!',
                html: 'Text or Content',
                confirmButtonClass: 'btn btn-primary',
                confirmButtonText: 'Your Text',
                buttonsStyling: false,
                onOpen: function () {
                    var audplay = new Audio(soundfile)
                    audplay.play();
                }
            })
