我有一个C＃程序，我写的在Windows和单声道下运行良好，除了我无法从Mono获得任何声音。 我知道64位机器和.Net无法发出系统蜂鸣声的问题，所以我们不要对此感到困惑！
我曾尝试使用Ubuntu Quantal和Raring运行Ubuntu Quantal和Raring的几台不同的Linux机器，没有声音，没有错误。
所以我从源代码编译了3.0.12版本，并且使用了3.x版本我尝试过崩溃。
所以，这是导致它崩溃的C＃行：
System.Media.SoundPlayer tagbeep = new System.Media.SoundPlayer("beep.wav");
tagbeep.Load();
if (tagbeep.IsLoadCompleted)
{
Console.WriteLine("I just beeped");
tagbeep.Play();
}
以下是导致此问题的Mono版本：
（我也尝试过3.0.6，结果相同）
Mono JIT compiler version 3.0.12 ((no/d6c5db8 Tue Jun 25 11:21:40 WST 2013)

所以，这是Mono崩溃时的输出：

把它放在这里感觉有点奇怪，但我被Mono网站引导到了这里。 这是我的第一篇文章，我检查了重复，我希望有人可以提供帮助。
即使您无法解决这个问题，我也非常想知道如何在64位机器上发出单声道系统蜂鸣声或发出哔声。
更新：
我发现了一种邪恶的方式。
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.EnableRaisingEvents=false;
proc.StartInfo.FileName = "aplay";
proc.StartInfo.Arguments = "-t wav beep.wav";
proc.Start();
