if语句条件正确但跳过代码不执行

Question

当firstMember 值为0时，执行两个button函数，这两个函数包括了绘图，返回该按钮是否被点击
但事实上并不会绘图，断点确实经过了，firstMember 为其他值时mciSendString的声音要在非常长的时间（几秒）之后才会发出

    if (firstMember == 0) {
        if (button(msg, 452, 418, 100, 38, NULL, NULL, WHITE, NULL, "叫地主")) {
            numLord ++;
            finallord = player;
            //叫地主.mp3
            //string str;
            //mciSendString(str.c_str(), 0, 0, 0);
            mciSendString("open audio/男叫地主.mp3 ", 0, 0, 0);
            mciSendString("play audio/男叫地主.mp3 ", 0, 0, 0);
        }
        if (button(msg, 729, 418, 100, 38, NULL, NULL, WHITE, NULL, "不叫")) {
            //不叫.mp3
            mciSendString("play audio/男不叫.mp3", 0, 0, 0);
        }
        while (1);
    }
    else if (firstMember == 1) {
        ifLord = rand() % 2;
        if (ifLord) {
            finallord = bot1;
            //叫地主.mp3
            mciSendString("play audio/男叫地主.mp3", 0, 0, 0);
            Sleep(100);
        }
        else {
            //不叫.mp3
            curMember++;
            finallord = member::nAn;
            mciSendString("play audio/男不叫.mp3", 0, 0, 0);
            Sleep(100);
        }
    }
    else if (firstMember == 2) {

            finallord = bot2;
            //叫地主.mp3
            
            Sleep(100);
        }
        else {

            mciSendString("open audio/男不叫.mp3 ", 0, 0, 0);

这个函数就是有一个缺点，打开mp3要很长时间，没有什么好的方法，只有提前播放
