Can someone help me?

我的代码是：

PlaySound("kenny g.WAV", NULL, SND_ASYNC);
}

You need to use the absolute path, make sure that you're sending a filename (use SND_FILENAME flag), and pause the program long enough to play the sound file (e.g., use getchar()). You need to link the winmm.lib library in your project settings, and #include windows.h and mmsystem.h in the header.
您需要使用绝对路径，确保您发送的是文件名（使用 SND_FILENAME 标志），并暂停程序足够长的时间来播放声音文件（例如，使用 getchar()）。您需要在项目设置中链接 winmm.lib 库，并在标题中链接 #include windows.h 和 mmsystem.h。
#include <windows.h>
#include <mmsystem.h>
int main() {
PlaySoundA((LPCSTR) "C:\kenny g.WAV", NULL, SND_FILENAME | SND_ASYNC);
getchar();
}

That should be it. Let me know, thanks!

应该是这样。让我知道，谢谢！

try adding -lwinmm to your compiler settings thingy. It worked for me. Just type that in the compiler options area and it will work.
尝试将 -lwinmm 添加到您的编译器设置中。它对我有用。只需在编译器选项区域中输入它，它就会起作用。

int main() {
PlaySound("kenny g.WAV", NULL, SND_ASYNC);
}
With the SND_ASYNCflag your program can (and it will) terminate immediatelly!
使用该SND_ASYNC标志，您的程序可以（并且会）立即终止！
Try PlaySound("kenny g.WAV", NULL, SND_SYNC);first to see if it works.
PlaySound("kenny g.WAV", NULL, SND_SYNC);首先尝试看看它是否有效。

Can you use absolute path and check if it is path error?
您可以使用绝对路径并检查它是否是路径错误吗？
Ex: PlaySound("C:\kenny g.WAV", NULL, SND_ASYNC);

you can test by PlaySound(TEXT("SystemStart"), NULL, SND_ALIAS);
您可以通过 PlaySound(TEXT("SystemStart"), NULL, SND_ALIAS); 进行测试。

Just in case it is unresolved yet! You need to include the two header files mentioned in previous comments, link the project to the required lib and place the sound file in the same folder as your .exe file (in case you are not using the full path)
以防万一它还没有解决！您需要包含前面注释中提到的两个头文件，将项目链接到所需的 lib 并将声音文件放在与 .exe 文件相同的文件夹中（以防您没有使用完整路径）

Try this code it works for me. Also For code::Block use winmm in linker settings.
试试这个代码它对我有用。同样对于 code::Block 在链接器设置中使用 winmm。
#include <iostream>
#include <windows.h>
#include <MMSystem.h>
int main(){
PlaySound(TEXT("your file path.wav") , NULL , SND_SYNC) ;
return 0;
}
