java - 在 Mac 上使用 Java 播放声音

Question

好的，在我发布任何代码之前，这是我的规范:

• 计算机:Macbook Air，2014 年初机型
• Java 版本:Java 8，Update 65(Java 控制面板说我使用的是推荐版本)
• 操作系统版本:OS X El Capitan，10.11.1

既然那已经结束了，我将终端用作控制台窗口，使用 java 运行，使用 javac 进行编译。我的项目中有一个类专门用于播放声音。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 {

        }
    }

}

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(我不得不使用全名，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。剪辑播放声音。

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，而 OS X 建议 Java 过渡到 AudioComponent.h。

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

Java Sound API 有效，但它在让 Jukebox 播放时输出:

这是因为 OpenJDK 为此绑定(bind)到 openal-soft，并且它目前依赖于 Carbon。

OpenJDK 上有一个 Unresolved 问题: https://bugs.openjdk.java.net/browse/JDK-8138754

它已在 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。

应该可以构建一个安装更新的 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，但我建议您的代码基于 Java Sound API example并将此消息记录为目前的已知问题，因为 openal-soft 已得到修复，其发布不在您的控制范围内。
