Question

好吧，在我发布任何代码之前，这是我的规格：

电脑：Macbook Air，2014年初型号
Java版本：Java 8，更新65（Java控制面板说我正在使用推荐版本）
操作系统版本：OS X El Capitan，10.11.1

现在已经不在了，我使用Terminal作为控制台窗口，java运行，javac进行编译。我的项目专门用于播放声音。完整的代码如下：

package javacoffeeadventure.audiomanager;

import java.io.*;
import javax.sound.sampled.*;
import javacoffeeadventure.io.FileIO;
import javacoffeeadventure.commandinterpreter.*;

public class AudioManager {

    public static void playSound(String soundName) {
        try {
            FileIO f = new FileIO();
            AudioInputStream ain = AudioSystem.getAudioInputStream(f.getURLForResource("sounds/" + soundName));
            Clip clip = AudioSystem.getClip();
            clip.open(ain);
            clip.start();
        } catch (Exception ex) {
            javacoffeeadventure.commandinterpreter.Console.sharedConsole().error("Exception while playing sound " + soundName + ": " + ex.getMessage());
        } finally {

        }
    }

}

WHERE ...

javacoffeeadventure是软件包的顶级名称
commandinterpreter.Console是一种使用控制台快速完成工作的方法（我必须使用全名，因为java.io.Console已经存在）
javacoffeeadventure.io.FileIO是处理资源和加载/保存文件的简单方法
我正在播放wav个文件

无论哪种方式，我都会使用javax.sound.sampled.AudioInputStream，javax.sound.sampled.AudioSystem和javax.sound.sampled.Clip播放声音。

调用clip.start()时，会发生以下错误：

2015-11-15 21:23:08.195 java[77192:2681680] 21:23:08.195 WARNING:  140: This application, or a library it uses, is using the deprecated Carbon Component Manager for hosting Audio Units. Support for this will be removed in a future release. Also, this makes the host incompatible with version 3 audio units. Please transition to the API's in AudioComponent.h.

这告诉我Java使用过时的框架CarbonComponent.h来播放声音，OS X建议Java过渡到AudioComponent.h。

是否有可用的解决方法，因此我可以播放声音而不使用弃用的方法并避免不必要的异常？

Java Sound API 正常工作，但在让Jukebox播放时会输出：

这是因为OpenJDK绑定到openal-soft，目前它依赖于Carbon。

OpenJDK存在未解决的问题： https://bugs.openjdk.java.net/browse/JDK-8138754

已在 openal-soft 的主分支中修复： https://github.com/kcat/openal-soft/issues/20

从 openal-soft 1.17.0 开始，它还没有发布，这是我写的最新版本。

应该可以构建一个较新的openal-soft安装来解决这个问题。它可能已经在Homebrew中提供。

您可以从源代码构建，但我建议您将代码基于Java Sound API example，并将此消息记录为已知问题，因为 openal-soft 已修复且其版本为在你的控制之外。
