听不到声音Android模拟器Mac

Question

我的Mac上的Android模拟器听不到任何声音。有时候，真的很少时间我能听到。我给你我的声音管理器的代码。但我认为它的配置问题

我从一个页面上复制了代码，他们说它可以工作。我已经尝试了大约5种不同的代码，但都不起作用。我的声音在WAV游戏中: 100k菜单800k

谢谢

我解决了它，

只需重新安装所有的eclipse和SDK即可。我在另一台电脑上试了试，工作正常。相同的代码

基本上，您必须在配置设置中设置一个标记，以告诉它要输出哪种类型的音频，以及输出哪种设备。这是一种痛苦。我在这里写道：

这在我的旧MacBook上起作用了。刚刚升级到Mac Air，解决方案已经改变，不确定，但-audio是现在的解决方案。当我让它工作时，我会在这里发帖。
