自定义通知声音不播放 windows 通用应用程序 8.1

Question

我想在收到通知时播放自定义声音，而不是自定义声音默认声音正在播放。这是怎么回事。甚至是正确路径上的音频。

 public void AddNotification(int t, String date,String idPrefix)
{
    ToastTemplateType toastTemplate = ToastTemplateType.ToastText02;
    XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(toastTemplate);

    DateTime dueTime = DateTime.Now;
    string period = String.Empty;

    switch (t)
    {
        case 0:
            period = "15min";
            dueTime = GetNotificationTime(date, dueTime, 15);
            break;
        case 1:
            period = "30min";
            dueTime = GetNotificationTime(date, dueTime, 30);
            break;
        case 2:
            period = "1hr";
            dueTime = GetNotificationTime(date, dueTime, 60);
            break;
        default: break;
    }

    XmlNodeList toastTextElements = toastXml.GetElementsByTagName("text");
    toastTextElements[0].AppendChild(toastXml.CreateTextNode("show time"));
    toastTextElements[1].AppendChild(toastXml.CreateTextNode("Watch show in " + period));

    //XmlNodeList toastImageAttributes = toastXml.GetElementsByTagName("image");

    //((XmlElement)toastImageAttributes[0]).SetAttribute("src", "ms-appx:///assets/CameraSelected.png");
    //((XmlElement)toastImageAttributes[0]).SetAttribute("alt", "Camera Selected");

    IXmlNode toastNode = toastXml.SelectSingleNode("/toast");
    ((XmlElement)toastNode).SetAttribute("launch", "LandingPage.xaml");

    XmlElement audio = toastXml.CreateElement("audio");
    audio.SetAttribute("src", "ms-appx:///Assets/Guitar.aifc");
     toastNode.AppendChild(audio);
    //launch tost immediatly

    ToastNotification toast = new ToastNotification(toastXml);
    ToastNotificationManager.CreateToastNotifier().Show(toast);

}

我在这里做错了什么。谁能指导我实施。

我想出了解决办法

它不支持 aifc 文件。我已将声音文件转换为 wav，现在它工作正常
