当我用linux(ubuntu 11.04)测试时，我用JAVA创建游戏，混音器只有一条线，所以我不能同时播放声音。我从net上得到pulseAudio有一条线路，这意味着它有无限的线路，所以我试着使用那个混音器。但是当我打开一行时，我得到了这个错误。

如何解决这个问题？

我也遇到过类似的错误。在这种情况下，PulseAudio混合器似乎不是线程安全的。我通过在AudioSystem.getSourceDataLine()调用上进行外部同步解决了这个问题。

我在我的linux box (mint)上也遇到了类似的问题，这在windows上是不存在的。我发现从openJDK和JRE切换到sunJDK和JRE解决了我的问题。
