Program halts when NAudio WaveOut.init();

Question

I'm making my own musicplayer with NAudio Library, and configuring playlist function.

Everything is OK, but I got a little problem to complete it.

When playback is completed, call playback function to play next music, and program halt.

I set breakpoint and execute line by line, and I found which line makes the program halt.

AudioFileReader _audioFileReader;
IWavePlayer _waveOutDevice = new WaveOut();
(...)
private void PlaybackStopped(object sender, EventArgs e)
{
    if (_manual_stop == false)
    {
        if (nowIndex + 1 == listMusic.Items.Count)
        {
            btnPlayCtrl.Text = "▶";
            return;
        }
        else
        {
            nowIndex++;
            playMusic();
        }
    }
    else
    {
        btnPlayCtrl.Text = "▶";
        return;
    }

}

private void playMusic()
{
    if (_paused == true)
    {
        _waveOutDevice.Play();
        _paused = false;
        return;
    }

    stopMusic();

    _audioFileReader = new AudioFileReader(listMusic.Items[nowIndex].Text);
    _waveOutDevice.Init(new WaveChannel32(_audioFileReader)); //It makes program halt

    getProperties(listMusic.Items[nowIndex].Text);
    _waveOutDevice.Play();

    _manual_stop = false;
}

I used 1.7.3.0 version of NAudio and tried to replace another copy of DLL, but it doesn't work.

You should only call Init once on an output device. Try closing the existing WaveOut device and creating a new one to play the next file.
