On a PC, while using Chrome. If I navigate to a song, it starts playing automatically. But while using Chrome on Android it doesn't play the song. I have to hit the play/pause button again to play the audio.
在 PC 上，同时使用 Chrome。如果我导航到一首歌，它会自动开始播放。但是在 Android 上使用 Chrome 时，它不会播放这首歌。我必须再次点击播放/暂停按钮才能播放音频。
Here is the code which runs, when you select the song to play:
这是当您选择要播放的歌曲时运行的代码：
audioPlayer.src=songurl[number];
audioPlayer.oncanplaythrough = "isAppLoaded";
audioPlayer.autoplay = "autoplay";
audioPlayer.addEventListener('ended',nextSong,false);
document.getElementById("player").appendChild(audioPlayer);
and here is the play/pause code.
这是播放/暂停代码。
if (audioPlayer.paused)
{
audioPlayer.play();
$("#pauseindicator").hide();
$("#playindicator").show();
}
else
{
audioPlayer.pause();
$("#pauseindicator").show();
$("#playindicator").hide();
}
Could it have some thing to do with the 'autoplay' variable? The default browser in Android plays the song immediately.
它可能与“自动播放”变量有关吗？Android 中的默认浏览器会立即播放歌曲。
Thanks.
谢谢。

Chrome does not allow applications to play HTML5 audio without an explicit action by the user, similar to how it is handled by iOS, but differently than the stock Android browser handles it.
Chrome 不允许应用程序在没有用户明确操作的情况下播放 HTML5 音频，类似于 iOS 的处理方式，但与普通 Android 浏览器的处理方式不同。
Autoplay is not honored on android as it will cost data usage.
安卓系统不支持自动播放，因为它会消耗数据流量。

In case someone bumps into this - Android version of Chrome in fact blocks autoplay function, but you can change settings of the browser. To do this, you have to enter chrome://flagsand set Disable gesture requirement for media playbackto on. It's impossible to force this setting via web, but if you're writing a dedicated web app like I did, you can use it.
万一有人碰到这个 - Android 版的 Chrome 实际上会阻止自动播放功能，但您可以更改浏览器的设置。为此，您必须输入chrome://flags并将媒体播放的禁用手势要求设置为开启。通过 Web 强制执行此设置是不可能的，但是如果您像我一样编写专用的 Web 应用程序，则可以使用它。

Add create.js to your page:
将 create.js 添加到您的页面：

and then launch sound this way:
然后以这种方式启动声音：
<script>
createjs.Sound.registerSound("./click.mp3", "x");
setTimeout(function () {
createjs.Sound.play("x");
}, 10000)
</script>
