在 Mac 上使用 Java 播放声音

Question

好的，在我发布任何代码之前，这是我的规格：

• 计算机：Macbook Air，2014 年初型号
• Java 版本：Java 8，Update 65（Java 控制面板显示我使用的是推荐版本）
• 操作系统版本：OS X El Capitan，10.11.1

现在不碍事了，我使用终端作为控制台窗口，java 运行，javac 编译。我的项目中有一个专门用于播放声音的课程。它的完整代码如下：

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 {

        }
    }

}

在哪里...

• javacoffeeadventure 是包的顶级名称
• commandinterpreter.Console 是一种使用控制台快速执行操作的方法（我必须使用全名，因为 java.io.Console 已经存在）
• javacoffeeadventure.io.FileIO 是一种处理资源和加载/保存文件的简单方法
• 我正在播放wav 文件

无论哪种方式，我都在使用javax.sound.sampled.AudioInputStream、javax.sound.sampled.AudioSystem 和javax.sound.sampled.Clip 来播放声音。

调用clip.start()时出现如下错误：

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 转换到 AudioComponent.h。

是否有可用的解决方法，这样我就可以在不使用已弃用的方法并避免不必要的异常的情况下播放声音？

Java Sound API有效，但它在让 Jukebox 播放时输出：

这是因为 OpenJDK 为此绑定到 openal-soft 并且它目前依赖于 Carbon。

OpenJDK 上有一个未解决的问题： https://bugs.openjdk.java.net/browse/JDK-8138754

已在 openal-soft 的 ma​​ster 分支中修复： https://github.com/kcat/openal-soft/issues/20

openal-soft 1.17.0 尚未发布，这是我撰写本文时可用的最新版本。

应该可以安装一个更新的 openal-soft 来解决这个问题。它可能已经在 Homebrew 中可用。

您可以从源代码构建，但我建议您将代码基于 Java Sound API example 并将此消息记录为目前已知的问题，因为 openal-soft 已修复且其发布不在您的控制。
