将此代码添加到Cordova Starter项目以重现我的问题：

    var playCounter = 0;
    function playMP3(){
      console.log("playMP3() counter " + playCounter);
      var my_media = new Media("app/www/test.mp3");//ressource buildAction == content
      my_media.play();
      playCounter++;

取消激活应用程序（关闭屏幕）
重新激活应用程序（打开屏幕）
->你还有一次机会

任何帮助都是受欢迎的，因为我从五月天起就被阻止了，我在任何地方都没有找到有用的信息

另外，你能告诉我这个代码在你的配置上是否有效吗

更新：添加演示代码Cordova 1.8.0rc1

使用全局变量。保持实例活动

结果

播放test2.mp3，可以很好地回放
根本不播放test.mp3
这是您播放的第一个有效文件

代码

  function onDeviceReady()
  {
  document.getElementById("welcomeMsg").innerHTML += "Cordova is ready! version=" + window.device.cordova;
  console.log("onDeviceReady. You should see this message in Visual Studio's output window.");
  my_media = new Media("app/www/test.mp3");//ressource buildAction == content
  my_media2 = new Media("app/www/test2.mp3");//ressource buildAction == content
  }

  var playCounter = 0;
  var my_media = null;
  function playMP3(){
    console.log("playMP3() counter " + playCounter);
    my_media.play();
    playCounter++;
  }

  var my_media2 = null;
  function playMP32(){
    console.log("playMP32() counter " + playCounter);
    my_media2.play();
    playCounter++;
  }

</script>

更新：Cordova 2.0.0

我用2.0.0的测试用例更新了Apache bug报告

有人能复制这个吗

链接到错误报告：

我看到您在第二次单击时收到一个IsolatedStorageException，这使我认为第一个

媒体

实例正在打开该文件，从而阻止再次访问该文件

我建议确保每个文件只创建一个

Media

实例，或者先看看是否有办法处置旧实例

以下是我将尝试的内容（但我尚未测试）：

var playCounter=0；
//已将my_媒体移到此处，因此不会重新创建它
var my_media=新媒体（“app/www/test.mp3”）//ressource buildAction==内容
函数playm3（）{
log（“playm3（）计数器”+播放计数器）；
我的媒体播放（）；
playCounter++；
}
[...]
单击以播放MP3
我不确定答案是正确的，因为我没有尝试过，但把它看作是一次头脑风暴。
首先使用var my_media=new media（src、onSuccess、onError）创建音频ctor，如果成功，只需播放它，如果出现错误，请首先尝试使用媒体释放它。释放代码
如果你知道要发布的其他事件或动作，那就更合适了
编辑：我刚刚注意到，您没有对媒体使用stop
，您也可以在需要时尝试使用它，例如playm3（）的开头，如果媒体不为空，请尝试先停止它
干杯。
我认为问题可能在于Silverlight每页只允许一个媒体实例的限制……而且由于PG/Cordova本质上是一个单页webBrowser实例，它只能有一个媒体实例。我正在构建一个XNA SoundEffect插件来解决这个问题。
差点忘了。。。这符合我的目的。希望有帮助；-）
WP7.5/Cordova 1.9.0
要求：据我所知，仅适用于.wav文件。我必须转换我的.mp3文件，因为它们会抛出丑陋的异常
插件：C#：
Javascript：使用：
//NOTE: Allows you to pre-load sound effect files

//initialize pgSoundFX plugin
if (!navigator.plugins) {
    console.log("plugIns do not exist!");
    navigator.plugins = {};
}

navigator.plugins.pgSoundFX.loadSound("www/audio/file1.wav", "item1");
navigator.plugins.pgSoundFX.loadSound("www/audio/file2.wav", "item2");
navigator.plugins.pgSoundFX.loadSound("www/audio/file3.wav", "item3");
    :
    :

//NOTE: Play whenever needed
navigator.plugins.pgSoundFX.playSound("item1");

当然，您的文件位置（www/audio/）、名称（file1等）和引用名称（item1等）都是您想要的。和大多数人一样，有很多方法可以改进这段代码……请放心。我的用例预加载了5个.wav文件，大小从28k到364k不等，并在整个用户游戏中播放它们。是一个Cordova bug

由PurpuleColle在其gitHub回购协议中解决。请参阅对错误报告的评论。
我尝试了GitHub的最新版本（1.8 rc1）。相同的问题。注意：问题与1.8相同，但错误不同。如果您关心此问题，我会将其报告给Apache:不适用于1.6.1。如果只播放一个文件，请使用1.8.0rc1。（不能使用其他媒体实例加载其他文件）。日志：System.Windows.dll中出现“System.ArgumentException”类型的第一次意外异常；错误：EL PARAARMetre EnSimeTo。但是你能按这个按钮多次按问题播放一个声音吗？播放多个不同的声音会让事情变得更复杂，因为你说一次不能有多个媒体实例。在每个播放按钮开始时，您需要检查my_media是否为null，如果不是null，则停止并可能释放（如@Onur_TOPAL所说），然后创建一个新实例。不管怎样，这是我的猜测。让我们澄清一下：只有第一个要播放的文件才能工作（如果你让实例保持活动状态，你可以多次播放）。如果您尝试播放其他文件（通过创建新的媒体实例），则无法播放。release（）.stop（）无法解决此问题。您可能需要提出新问题或更改此问题，以反映您想要播放多个不同的声音。此问题与一个mp3有关，因为这是再现错误的最简单情况。显然，我的应用程序中有不止一个mp3，我想不止一次地播放它们。也许我不清楚，我不会在同一时间播放它们（混音器），而是一个接一个地播放（在btn上单击）。谢谢你的输入。我试过打电话了，停。在重新创建对象之前释放并“=null”：不成功。如果您的代码仍然与问题中的代码相同（我的意思是媒体变量是本地的），这些函数将无法工作。你应该像奥斯汀的回答一样把它定义为全球性的。如果它作为全局变量仍然不起作用，我完全不知道。谢谢你的回答。更新：从2.1开始，文件会播放，但是回调实现有缺陷。请参阅错误报告：更新：错误已修复并合并。
