Volume props is not working

[Sonukr]

I am trying to control the volume of react-sound but, it looks alike volume props is not being accepted by component. here is the same code which I wrote and your NPM props.

My code:

this.state = {
  volume: 10
}

<Sound
           url={this.prepareUrl(this.state.track.stream_url)}
           playStatus={this.state.playStatus}
           onPlaying={this.handleSongPlaying.bind(this)}
           playFromPosition={this.state.playFromPosition}
           volume={this.state.volume}
           onPause={() => console.log('Paused')}
           onResume={() => console.log('Resumed')}
           onStop={() => console.log('Stopped')}
           onFinishedPlaying={this.handleSongFinished.bind(this)}/>

 <Player         
  onVolumeUp={() => this.setState({volume: volume >= 100 ? volume : volume+10})}
  onVolumeDown={() => this.setState({volume: volume <= 0 ? volume : volume-10})}
 />

Evan these log is not working.

Some props from your NPM :

{
    key: 'propTypes',
    value: {
      url: _react.PropTypes.string.isRequired,
      playStatus: _react.PropTypes.oneOf(Object.keys(playStatuses)).isRequired,
      position: _react.PropTypes.number,
      playFromPosition: _react.PropTypes.number,
      onLoading: _react.PropTypes.func,
      onPlaying: _react.PropTypes.func,
      onFinishedPlaying: _react.PropTypes.func
    },
    enumerable: true
  }, {
    key: 'defaultProps',
    value: {
      playFromPosition: 0,
      onLoading: noop,
      onPlaying: noop,
      onFinishedPlaying: noop
    },
    enumerable: true
  }

can you please help me to understand this why I am not able to control the sound. am I missing something or something else?
