【问题描述】：

我想在我的程序中同时播放多个声音。看到在我之前很多人都问过这个问题，我浏览了他们，并决定尝试在不同的线程上播放声音。但是，我仍然遇到相同的问题，即当前播放的声音会出现新的声音。

我是否犯了错误，或者我是否误解了多线程这将是可能的？ 实现这一目标的正确方法是什么？

 public class SoundManager

    private const int NUM_EFFECT_CHANNELS = 8;
    private const int NUM_AMBIENT_CHANNELS = 2;
    private static Thread[] ambientSounds = new Thread[NUM_AMBIENT_CHANNELS];
    private static Thread[] soundEffects = new Thread[NUM_EFFECT_CHANNELS];
    private static bool[] isPlaying = new bool[NUM_EFFECT_CHANNELS];
    private static bool[] isAmbientPlaying = new bool[NUM_AMBIENT_CHANNELS];

    #region public

    public static void PlayAmbientSound(string soundFileName)
    
        for (int channel = 0; channel < NUM_AMBIENT_CHANNELS; channel++)
        
            if (isAmbientPlaying[channel])
                continue;
            ambientSounds[channel] = new Thread(() =>  ambientPlayer(soundFileName, false, channel); );
            isAmbientPlaying[channel] = true;
            ambientSounds[channel].Start();

【参考方案1】：

SoundPlayer 使用 Windows MCI 并且不是线程安全的。您可以使用他们的异步方法，但不能同时播放多个流或不能用于同时播放声音。见这里：1

您需要使用另一个 AudioLibrary，例如 DirectX 或 OpenAL。
