<ul>

Also do not forget launch AVD using Cold Boot start.

blocks|key|374093|text|快速修复:如果可以的话，尝试使用一个实际的Android来测试应用程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|374094|切换到实际的android设备进行测试有两个很好的理由：|374095|1.+Emulator+eats+up+device+memory+and+results+would+mostly+vary+on+an+actual+android.

Quick Fix: Try using an actual Android for testing out applications if you can.

Two good reasons to switch to an actual android device for testing:

<pre><code>1. Emulator eats up device memory and results would mostly vary on an actual android.
2. Testing on an actual device is a better way of ensuring that the application 
 behaves as expected on the actual device.
</code></pre>

Sorry about not providing you an actual answer to the asked question, rather an alternative. But when I started programming for android devices, the android emulator would take up a lot of memory and time, due to which I decided to move to an actual android device early(I probably saved a lot of time and frustration in the long run, since I had only 4 GB RAM and Android Studio is quite memory hungry too).

So I generally suggest people to use an actual device(probably a Moto or a Nexus, since they are stock Android Devices) instead of testing on emulators also because of the occasional compatibility issues like your current sound issue.

Good luck either ways :)

bluetooth headphone connected to iMac(macOS Sierra v 10.12.2) and system audios could be heard from headphone.

but Android Emulator audio not connect to headphone and play sound on iMac speaker.

Even when the voice of the iMac is mute , Emulator sound could be heard from speaker.

蓝牙耳机连接到iMac(macOS Sierra 10.12.2)和系统音频可以从耳机听到。但安卓仿真器音频没有连接到耳机并在iMac扬声器上播放声音。即使iMac的声音是无声的，从扬声器中也可以听到仿真器的声音。
