使用循环 c# 同时播放两个声音

我有一个背景音乐，还有一个按钮，正在播放1~2秒的音效。我想要的是使背景音乐即使在播放按钮声音后仍会继续播放。

目前，它正在永久停止背景音乐以播放声音按钮。

这是我现在拥有的当前解决方案

private void LoginGUI_Load(object sender, EventArgs e)
{
    try
    {
        string filename = @"..'..'Soundtracks'The Boy Who Shattered Time.wav";
        Player = new System.Media.SoundPlayer(filename);
        Player.PlayLooping();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message, "Unable to play soundtrack.");
    }
}

这是按钮

public virtual void getButtonSound()
{
    try
    {
        string filename = @"..'..'Soundtracks'demacia.wav";
        Player = new System.Media.SoundPlayer(filename);
        Player.PlaySync();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message, "Unable to play soundtrack.");
    }
}

new System.Threading.Thread(() => {
        var c = new System.Windows.Media.MediaPlayer();
        c.Open(new System.Uri(@"..'..'Soundtracks'The Boy Who Shattered Time.wav"));
        c.PlayLooping();
    }).Start();

new System.Threading.Thread(() => {
        var c = new System.Windows.Media.MediaPlayer();
        c.Open(new System.Uri(@"..'..'Soundtracks'demacia.wav"));
        c.Play();
    }).Start();
