我们的 Java 应用程序定期播放简短的通知声音（响应用户操作）。在某些硬件上，我们的应用程序将在第三次或第四次短声后锁定。我们必须pkill java恢复。
我们在大约 40 台计算机上安装了该应用程序。全部都运行Linux。一半安装了 Kubuntu 12.04，一半安装了 Linux Mint 11。所有 Linux Mint 11 机器都工作正常，并且 Java 应用程序播放声音而不会锁定。
最初（从 12.04 版本开始）所有 Kubuntu 机器都运行良好。
在更新后的某个时刻，Kubuntu 机器在播放声音时开始锁定。如果我们关闭应用程序中的声音通知选项，这是一个解决方法。该应用程序不会锁定。但用户想要的是声音。
当我们发现问题时，我们停止在 Kubuntu 机器上运行更新，所有没有更新的机器（几个月前）继续从我们的应用程序播放声音，而应用程序不会冻结。
即使在更新的 Kubuntu 机器上，所有硬件上也不会出现锁定问题。例如，在 Thinkpad X220 平板电脑上，我们应用程序中的声音可以正常工作。但在 ThinkPad E430 上，在应用程序中启用声音会导致应用程序冻结。
我们无法发现其中的模式。是什么导致了最新的 Linux 和某些硬件上的锁定，而较旧的 Linux 在我们使用的所有硬件上都很好？
这是我们在其中的一些硬件的信息确实有问题：

答案1
我之前使用 sun.audio.AudioStream 和 sun.audio.AudioPlayer 在 Linux 上的 Java 中播放声音获得了最佳结果。这些是“内部”课程，不推荐，但它们对我来说比其他课程效果更好（多年来）。直到出现了这个问题。
我的新解决方案就是这样：Runtime.getRuntime().exec(mediaPlayerCommand + fileName);
对于媒体播放器，我可以play在 OpenSuse 或mplayerUbuntu 上使用。我只需将该命令放置在目标操作系统上的配置文件中，它就可以很好地工作。
