android - Android 模拟器 Mac 听不到声音

Question

我在 Mac 的 Android 模拟器中听不到任何声音。有时，我能听到的时间很少。我给你我的声音管理器代码。但我认为它的配置问题

我从他们说有效的页面上复制了代码。我已经尝试了大约 5 种不同的代码，但都没有用。我的声音在 WAV 游戏中:100k 菜单 800k

谢谢

基本上，您必须在配置设置中设置一个标志来告诉它要输出哪种音频以及使用什么设备。这很痛苦。我在这里写道:

这适用于我的旧 MacBook。刚升级到 Mac Air，解决方案已更改，不确定，但 -audio 现在是解决方案。当我开始工作时，我会在这里发布。
