这是我在 Ubuntu 11.04 上找到的混音器，

Name: PulseAudio Mixer 
Vendor: IcedTea 
Version: 0.02 
Description: the ear-candy mixer

当我使用 linux(ubuntu 11.04) 进行测试时，我收到此错误，

我使用 JAVA 创建游戏，混音器只有 1 行，所以我无法同时播放声音。我从网上得到，pulseAudio 有 -1 行，这意味着它有无限行，所以我尝试使用该混音器。但是当我打开一行时，我收到了该错误。

如何解决这个问题？？？

我有类似的错误。看来 PulseAudio Mixer 在这种方式下不是线程安全的。我通过外部同步 AudioSystem.getSourceDataLine() 调用解决了这个问题。

I've got a similar error. It seems that the PulseAudio Mixer is not thread safe in this manner. I solved it by externally synchonizing on the AudioSystem.getSourceDataLine() call.

我在我的 linux box (mint) 上也遇到了类似的问题，但在 Windows 上没有发生。我发现从 openJDK 和 JRE 切换到 sunJDK 和 JRE 解决了我的问题。

你可以去这里https://askubuntu.com/questions/21131/how-to- Correctly-remove-openjdk-and-jre-and-set-the-system-use-only-and-only-sun了解更多信息。

I had a similar issue as well on my linux box (mint) which was not happening on windows. I found that switching from openJDK and JRE to sunJDK and JRE solved my problem.
