Android media player stops playing while streaming mms protocol?

My android application plays a radio through MMS Stream using AudioTrack class as described here

The Problem is that after playing first chunk the device doesn't get any audio output.

Here is the logcat info that may be useful

Here is the code (It's the method itself which called periodically from C code)

boolean b = false;
Log.i("Hello", "There");
if (at != null) {
    Log.i("Comparing", "" + at.getPlayState());
    Log.i("Paused", "" + AudioTrack.PLAYSTATE_PAUSED);
    Log.i("Playing", "" + AudioTrack.PLAYSTATE_PLAYING);
    Log.i("Stopped", "" + AudioTrack.PLAYSTATE_STOPPED);

    b = at.getPlayState() != AudioTrack.PLAYSTATE_PLAYING;
}
try {
    if (!b) {
        int intSize = android.media.AudioTrack.getMinBufferSize(33075,
                AudioFormat.CHANNEL_CONFIGURATION_STEREO,
                AudioFormat.ENCODING_PCM_16BIT);
        at = new AudioTrack(AudioManager.STREAM_MUSIC, 33075,
                AudioFormat.CHANNEL_CONFIGURATION_STEREO,
                AudioFormat.ENCODING_PCM_16BIT, intSize * 20,
                AudioTrack.MODE_STREAM);
    }
    if (at == null) {
        Log.d("TCAudio", "audio track is not initialised ");
        return;
    }

    // 512 kb
    // Reading the file..
    byte[] byteData = null;
    if (file == null)
        file = new File("/sdcard/outmms.wav");
    int size = (int) file.length();

    Log.i("Size", "" + size);

    byteData = new byte[size];
    FileInputStream in = null;
    try {
        in = new FileInputStream(file);
        in.read(byteData);

        // if (!b) {
        at.play();
        // }
        at.write(byteData, offset, byteData.length);
        offset += byteData.length;
        Log.i("Offset", "" + offset);
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
} catch (Exception e) {
