Mono c＃SoundPlayer不起作用

Question

我尝试从安装了Raspbian的Raspberry Pi 3播放声音。我已经安装了单声道。我在Windows上测试过，运行良好。但是在Raspbian上运行时。我没有收到任何错误消息，也没有声音。

public void PlaySound()
{
    try
    {
        using (var file = new FileStream("example.wav",
            FileMode.Open, FileAccess.Read, FileShare.Read))
        {
            var player = new SoundPlayer(file);
            player.PlaySync();
        }
    }
    catch (Exception e)
    {
        Console.WriteLine("Sound failed to play");
    }
}

单声道版
