推荐答案

没有，这是不可能的。

插件很多可以使声音，他们都做它自己的方式。有没有包罗万象的在这里。

Lots of plugins can make sound, and they all do it in their own way. There is no catch-all here.

也许在哪里使用Chrome等浏览器，使一个单独的进程为每个页面的应用程序时使用的声音实际上是保持轨道，和Vista / 7，你可能有更多的运气。这将涉及搞清楚哪些进程正在播放声音，然后计算出每个进程加载了什么网页。通过JavaScript虽然？没办法。

Perhaps on Vista/7 where applications sound usage is actually kept track of, and when using a browser like Chrome that makes a separate process for each page, you might have more luck. It would involve figuring out which processes are playing sound, then figuring out what page each process had loaded. Through JavaScript though? No way.
