一、前言
还是不想写前言的，这边是接着windows下监听系统扬声器、麦克风的音量、静音事件接着写的。话不多说，直接上代码。
值得注意的是，里面使用object C写的。

二、实现
以下代码保证可用，各位可以根据需要进行修改
1.接口
void addPlayoutListener();void removePlayoutListener();void addRecodingListener();void removeRecodingListenr();//静态方法，将系统事件通过以下回调回来//麦克风静音事件static OSStatus inputMutePropertyListenerProc( AudioObjectID inObjectID,UInt32 inNumberAddresses,const AudioObjectPropertyAddress inAddresses[],void* inClientData);//麦克风音量事件static OSStatus inputVolumePropertyListenerProc( AudioObjectID inObjectID,UInt32 inNumberAddresses,const AudioObjectPropertyAddress inAddresses[],void* inClientData);//扬声器静音事件static OSStatus outputMutePropertyListenerProc( AudioObjectID inObjectID,UInt32 inNumberAddresses,const AudioObjectPropertyAddress inAddresses[],void* inClientData);//扬声器音量事件static OSStatus outputVolumePropertyListenerProc( AudioObjectID inObjectID,UInt32 inNumberAddresses,const AudioObjectPropertyAddress inAddresses[],void* inClientData);
2.实现
void AudioDeviceMac::addPlayoutListener(){SpeakerMute(_bSpeakerMute);SpeakerVolume(_nSpeakerVolume);AudioObjectPropertyAddress volumeaddress = {kAudioHardwareServiceDeviceProperty_VirtualMasterVolume,kAudioDevicePropertyScopeOutput,kAudioObjectPropertyElementMaster};//_outputDeviceID 输出设备idOSStatus relsult = AudioObjectAddPropertyListener(_outputDeviceID, &volumeaddress, &AudioDeviceMac::outputVolumePropertyListenerProc, this);WEBRTC_TRACE(kTraceInfo, kTraceAudioDevice, 0, "AudioDeviceMac::addPlayoutListener Volume result:%d", relsult);AudioObjectPropertyAddress muteaddress = {kAudioDevicePropertyMute,kAudioDevicePropertyScopeOutput,kAudioObjectPropertyElementMaster};relsult = AudioObjectAddPropertyListener(_outputDeviceID, &muteaddress, &AudioDeviceMac::outputMutePropertyListenerProc, this);WEBRTC_TRACE(kTraceInfo, kTraceAudioDevice, 0, "AudioDeviceMac::addPlayoutListener mute result:%d", relsult);}void AudioDeviceMac::removePlayoutListener(){AudioObjectPropertyAddress volumeaddress = {kAudioHardwareServiceDeviceProperty_VirtualMasterVolume,kAudioDevicePropertyScopeOutput,kAudioObjectPropertyElementMaster};OSStatus relsult = AudioObjectRemovePropertyListener(_outputDeviceID, &volumeaddress, &AudioDeviceMac::outputVolumePropertyListenerProc, this);WEBRTC_TRACE(kTraceInfo, kTraceAudioDevice, 0, "AudioDeviceMac::removePlayoutListener Volume result:%d", relsult);AudioObjectPropertyAddress muteaddress = {kAudioDevicePropertyMute,kAudioDevicePropertyScopeOutput,kAudioObjectPropertyElementMaster};relsult = AudioObjectRemovePropertyListener(_outputDeviceID, &muteaddress, &AudioDeviceMac::outputMutePropertyListenerProc, this);WEBRTC_TRACE(kTraceInfo, kTraceAudioDevice, 0, "AudioDeviceMac::removePlayoutListener mute result:%d", relsult);}void AudioDeviceMac::addRecodingListener(){MicrophoneMute(_bMicMute);MicrophoneVolume(_nMicVolume);AudioObjectPropertyAddress volumeaddress = {kAudioHardwareServiceDeviceProperty_VirtualMasterVolume,kAudioDevicePropertyScopeInput,kAudioObjectPropertyElementMaster};//_inputDeviceID 输入设备idOSStatus relsult = AudioObjectAddPropertyListener(_inputDeviceID, &volumeaddress, &AudioDeviceMac::inputVolumePropertyListenerProc, this);WEBRTC_TRACE(kTraceInfo, kTraceAudioDevice, 0, "AudioDeviceMac::addRecodingListener Volume result:%d", relsult);}void AudioDeviceMac::removeRecodingListenr(){AudioObjectPropertyAddress volumeaddress = {kAudioHardwareServiceDeviceProperty_VirtualMasterVolume,kAudioDevicePropertyScopeInput,kAudioObjectPropertyElementMaster};OSStatus relsult = AudioObjectRemovePropertyListener(_inputDeviceID, &volumeaddress, &AudioDeviceMac::inputVolumePropertyListenerProc, this);WEBRTC_TRACE(kTraceInfo, kTraceAudioDevice, 0, "AudioDeviceMac::removeRecodingListenr Volume result:%d", relsult);}OSStatus AudioDeviceMac::inputMutePropertyListenerProc( AudioObjectID inObjectID,UInt32 inNumberAddresses,const AudioObjectPropertyAddress inAddresses[],void* inClientData){AudioDeviceMac* ptrThis = (AudioDeviceMac*)inClientData;for(UInt32 addressIndex = 0;
