Google chrome extension Chrome扩展，在背景脚本中播放声音

我想播放Chrome扩展的声音，但我听说内容脚本不能播放声音。所以我把这段代码放在我的背景脚本中：

var audio = new Audio("alert.ogg");
audio.play();

但仍然没有声音。从_generated_backgound_page.html的控制台，我可以检查网络选项卡，并看到声音文件已成功加载，但我什么也没听到

另外，在另一个HTML页面中，我可以加载另一个Javascript，其中包含上述代码，并且可以正常工作（我可以听到声音）

它出现在背景脚本中的事实似乎使它失败了。另外，请注意，我没有与背景脚本关联的背景页面。那有关系吗

---

编辑：问题已解决。上面的代码可以工作，但我忘了听正确的声音输出通道

您可以使用javascript生成背景页面。我认为声音必须在html页面中才能加载和播放

这应该起作用：

我使用了base64音频文件，但您也可以使用普通文件。

这只是一个愚蠢的错误。。。我的音频输出已更改为另一个声音设备。也许我应该删除这个问题？你们应该以某种方式将一个问题标记为“无效”。但并没有办法标记它。只需编辑你们的问题：写下它是无效的，并写下你们是如何解决它的。与我的问题一样，你应该做以下操作之一：1）回答你自己的问题并将其标记为已接受；2）如果你觉得该问题对其他人没有帮助，则完全删除该问题。它会出现错误“play（）failed，因为用户没有先与文档交互”。
