I'M developing a voice chat App stream voice over tcp protocol.

when client connects to server start Repeated beeps. too noisy...!no clear voice hearing... will you take a look at my code?

client :

PHP Code:
public void startStreaming() {

   Thread streamThread = new Thread(new Runnable() {

       public void run() {
            try {

                int minBufSize =AudioRecord.getMinBufferSize(sampleRate, channelConfig, audioFormat);
                Log.d("VD ", "Bufer intioalised "+minBufSize);
               // DatagramSocket socket = new DatagramSocket();
                byte[] buffer=new byte[minBufSize];

                Log.d("VS","Buffer created of size .c" + minBufSize);
              // DatagramPacket packet;

                final InetAddress destination = InetAddress.getByName(target.getText().toString());
                Socket socket=new Socket(destination,port);

               DataOutputStream dos=new DataOutputStream(new BufferedOutputStream(socket.getOutputStream()));
                Log.d("VS", "Address retrieved.c");

                if (minBufSize != AudioRecord.ERROR_BAD_VALUE) {
                	recorder = new AudioRecord(MediaRecorder.AudioSource.MIC,sampleRate,channelConfig,audioFormat,minBufSize*=10);
                Log.d("VS", "Recorder initialized.c");}

                if (recorder.getState() == AudioRecord.STATE_INITIALIZED){
                	Log.d("VS", "Recorder working....c");

                BufferedWriter input;
                while(status == true) {

                    //reading data from MIC into buffer
                  int  bufferReadResult = recorder.read(buffer, 0, buffer.length);
                 for (int i=0; i < bufferReadResult; i++) {
                    //packet = new DatagramPacket (buffer,buffer.length,destination,port);
                   // socket.send(packet);
                  // Log.d("", "wrote and "+buffer.toString().getBytes()+" socket: "+socket.getOutputStream());
server :

PHP Code:
public void startStreaming() {
    Thread streamThread = new Thread(new Runnable() {

        public void run() {

        	  try {

                  int  minBufSize =640;//recorder.getMinBufferSize(sampleRate,channelConfig,audioFormat);

                 ServerSocket serversocket = new ServerSocket(50005);

                   // DatagramSocket socket = new DatagramSocket(50005);

                    byte[] buffer = new byte[640];

                        if (minBufSize != AudioRecord.ERROR_BAD_VALUE) {

                            speaker = new AudioTrack(AudioManager.STREAM_MUSIC,sampleRate,channelConfig,audioFormat,minBufSize*=10,AudioTrack.MODE_STREAM);

                            Log.d("VR", "spekaer playing...");
                  //  }

                        Log.d("VR", ""+status);
                        BufferedReader input;
                        InputStream is;
                        ObjectInputStream ois;
                        ByteArrayInputStream baiss;
                       socket = serversocket.accept();
                         DataInputStream dis=new DataInputStream(new BufferedInputStream(socket.getInputStream()));

                              while(status == true) {

                                    //DatagramPacket packet = new DatagramPacket(buffer,buffer.length);

                                //  InputStream in = socket.getInputStream();

                                 // Log.d("content :", socket.getOutputStream().toString());

                                  int i=0;
                                  while (dis.available() > 0 && i < buffer.length) {
                                      buffer[i]=(byte) dis.readShort();

	                             Log.d("VR", "Writing buffer content to speaker.s");

I'VE tried this with udp .do not suggest udp please
