我正在使用相同的耳机在macOS中设置离线音频播放和录制功能，以进行播放和录制。为了获取活动设备ID以及播放和录制的默认设备ID，我使用了核心音频框架fn AudioObjectGetPropertyData，它可以正确检测播放deviceID，但会抛出错误“ HALC_ShellDriverPlugIn :: Open：无法获取记录设备ID的指向Open例程的指针”和“ AudioObjectGetPropertyData：没有具有给定ID的对象”

AudioObjectPropertyAddress   prAddress;
AudioObjectID def_input_id;

        prAddress.mSelector = kAudioHardwarePropertyDefaultInputDevice;
         prAddress.mScope    = kAudioObjectPropertyScopeGlobal;
         prAddress.mElement  = kAudioObjectPropertyElementMaster;
         size_l = sizeof(AudioObjectID);

/*To get the def_input_id*/
         err = AudioObjectGetPropertyData(kAudioObjectSystemObject,&prAddress,NULL,&size_l,&def_input_id);

         printf("Final value of def_put_id = %d\n",def_output_id);

/*to detect the device name from def_input_id*/
         prAddress.mSelector = kAudioDevicePropertyDeviceName;
         prAddress.mScope = kAudioObjectPropertyScopeGlobal;
         prAddress.mElement = kAudioObjectPropertyElementMaster;
         size_l = sizeof(aud_dev_info.cap_dev_to_use);


         err = AudioObjectGetPropertyData(def_input_id,aud_dev_info.cap_dev_to_use);

/* For play ID,I replace kAudioHardwarePropertyDefaultInputDevice with kAudioHardwarePropertyDefaultOutputDevice and 'def_input_id' to 'def_output_id'

预期：def_input_id的最终值= 40（一些非零值）

获得：HALC_ShellDriverPlugIn :: Open：无法获得指向Open例程的指针           def_input_id的最终值= 0
