通过web服务暂停流媒体广播

我有一个问题一旦我开始播放电台暂停功能不起作用这是我的代码

public class player
{
   Stream ms = new MemoryStream ( );
   WaveStream blockAlignedStream;
   IWavePlayer waveOut = new WaveOut ( WaveCallbackInfo . FunctionCallback ( ) );`
   public void play ( string url )
    {
       new Thread ( delegate ( object o )
       {
           // http://www.samisite.com/sound/cropShadesofGrayMonkees.mp3
           var response = WebRequest . Create ( url ) . GetResponse ( );
           using ( var stream = response . GetResponseStream ( ) )
           {
              byte[] buffer = new byte [ 65536 ]; // 64KB chunks
              int read;
              while ( ( read = stream . Read ( buffer , 0 , buffer . Length ) ) > 0 )
                {
                   var pos = ms . Position;
                   ms . Position = ms . Length;
                   ms . Write ( buffer , 0 , read );
                   ms . Position = pos;
                }
            }
    } ) . Start ( );
    // Pre-buffering some data to allow NAudio to start playing
    while ( ms . Length < 65536 * 5 )  // *10
        Thread . Sleep ( 1000 );
    ms . Position = 0;
    blockAlignedStream = new BlockAlignReductionStream ( WaveFormatConversionStream . CreatePcmStream ( new Mp3FileReader ( ms ) ) ); 
    this.waveOut . Init ( blockAlignedStream );
    this.waveOut . Play ( );
    while ( waveOut . PlaybackState == PlaybackState . Playing )
        {
        System . Threading . Thread . Sleep ( 100 );
        }
    } 
public void stop ( ) 
  {
   this.waveOut . Stop ( );
   this.waveOut . Dispose ( );
   this.waveOut = null;  
   }

然后我在webmethod中调用它，像这样

player mp3=new player ( );
[WebMethod]
 // http://streaming.radio.funradio.fr/fun-1-44-128
public void play(string url)
{
   mp3.play ( url );
}
[WebMethod]
public void pause (  )
{
   mp3 .pause();
}

有时屏幕消息显示此错误:"WaveOut设备未在WaveOut. finalize()关闭"

当我启动暂停函数时，我发现了问题，它使用参数"waveOut"，因为它没有在播放函数中修改，我需要找到一种方法来获得它们之间的连接。有什么想法吗!!!!
