1.接受广播

2.AudioSystem.cpp : setDeviceConnectionState

3.通过Binder调用AudioPolicyService  setOutputDevice --->setParameters

4.AudioFlinger.cpp：setParameters

5.android::AudioFlinger::PlaybackThread::threadLoop()

6.AudioFlinger::MixerThread::checkForNewParameters_l

7.ALSADevice::switchDevice       hardware/qcom/audio/alsa_sound/ALSADevice.cpp

疑问：为什么要调用两次setForceUse
