当我使用 linux(ubuntu 11.04) 进行测试时，我使用 JAVA 创建游戏，混音器只有 1 条线，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，我收到了这个错误。

如何解决这个问题？？？

最佳答案

我也遇到了类似的错误。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。

关于java - 在linux(PulseAudio)上使用混音器打开一行时得到java.lang.IllegalStateException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/6831193/
