Dynamically changing src doesn't change duration

[PideaLtd]

Feature Proposal

I'm putting together a web page that receives JSON data containing, among other things, a URL to an MP3. The JSON is pushed via websockets to the page.

When the page first loads I need to play a clip to allow the browser to permit audio so I play a 2 second silent MP3.

Using the solution outlined here:

#825

I can use a single instance of Howler and can change the audio source but the duration does not change so only the first 2 seconds of my clips play.

If I increase the size of the silent MP3 file that I first play to 10 seconds then reload the page, the first 10 seconds of my clips play but they can vary in length from 2 to 60 seconds.

I've tried changing the proposed changeSrc function so that:

self.unload(true);

becomes:

self.unload(false);

but that makes no difference. Is there a way to force Howler to pick up the new duration ?

Possible Implementation

loadイベントが発火してから処理をしたらどうなるんだろうか？

要するにこういうこと

function changeSrc(howl, src) {
    return new Promise((resolve, reject) => {
        howl.unload();
        howl.once("load", () => resolve(howl));
        howl.once("loaderror", (id, error) => reject({id, error}));
        howl._src = src;
        howl.load();
    });
}

（どうでもいいがunload関数は引数を取らない。）
（そもそもHowler.jsは自動的にオーディオを許可すると思う。）
（Howlオブジェクトを再生成するのは駄目なのだろうか？XY問題では？）
（html5プロパティはtrue？false？）
