Loads a sound from a file url.
The file extension in the url will be replaced according to the browser's
capability to playback certain kinds of audio types. For example if the
url ends with the 'mp3' extension and the browser does not support mp3
playback, the file extension will be replaced with 'ogg' or 'ac3'. You
can customize this behavior by changing the soundLoadOptions.
var sound = await Sound.load("assets/audio/hello.mp3");
sound.play();
