我有一个我编写的 C# 程序，它在 windows 和单声道下运行良好，除了我无法从 Mono 中获得任何声音。我知道 64 位机器和 .Net 无法发出系统哔声的问题，所以我们不要对此感到困惑！
我已经在几台运行 Ubuntu Quantal 和 Raring 的不同 Linux 机器上进行了尝试，并使用了普通的单声道版本，没有声音，也没有错误。
所以我从源代码编译了 3.0.12 版本，并且我尝试过的两个 3.x 版本都崩溃了。
因此，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();
}
这是导致此问题的 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)

把它放在这里感觉有点奇怪，但我是被 Mono 网站引导到这里的。这是我的第一篇文章，我检查了重复项，希望有人能提供帮助。
即使您无法解决这个确切的问题，我也很想知道如何使单声道系统发出哔哔声或在 64 位机器上播放哔声。
更新：
我找到了一种不圣洁的方法来做到这一点。
