private setOutputDeviceChangeCallback() { 
  if (!this.audioRenderer) { 
    return; 
  } 
  this.audioRenderer.on('outputDeviceChangeWithInfo', this.outputDeviceChangeCallback); 
} 
 
private outputDeviceChangeCallback: (deviceChangeInfo: audio.AudioStreamDeviceChangeInfo) => void = 
  (deviceChangeInfo: audio.AudioStreamDeviceChangeInfo) => { 
    Logger.info(TAG, `DeviceInfo id: ${deviceChangeInfo.devices[0].id}`); 
    Logger.info(TAG, `DeviceInfo name: ${deviceChangeInfo.devices[0].name}`); 
    Logger.info(TAG, `DeviceInfo address: ${deviceChangeInfo.devices[0].address}`); 
    Logger.info(TAG, `Device change reason: ${deviceChangeInfo.changeReason}`); 
    if (deviceChangeInfo.changeReason === audio.AudioStreamDeviceChangeReason.REASON_OLD_DEVICE_UNAVAILABLE) { 
      // 旧设备不可用，暂停播放 
      Logger.info(TAG, `Device change reason: ${deviceChangeInfo.changeReason}`); 
      this.pause(); 
    } 
  }
