Short summary tied to the replies already here: there are two broad ways to "run" audio from C — hand the file off to an external player (quick, limited control) or open/decode the file and send PCM to the audio device (more work, full control). 's quick-player idea is fine for one-off tests; pointed to an example; was on the right track recommending libraries. Below are practical, current options and small examples.

For native Windows WAV playback the OS API is easiest. The example below uses the multimedia API to play a WAV file asynchronously; link with winmm.lib and see the Microsoft docs for the function used.

#include <windows.h>
#include <mmsystem.h>

#pragma comment(lib, "winmm.lib")

int main(void) {
    PlaySoundA("C:\\path\\to\\sound.wav", NULL, SND_FILENAME | SND_ASYNC);
    Sleep(3000); // keep program alive while sound plays
    return 0;
}

For cross-platform code, use a library that exposes device output and helpers for loading WAV. SDL2 is a common, simple choice; it lets you load WAV data and queue it to the audio device. The SDL audio API is documented at the SDL wiki.

Compressed formats (MP3, AAC, OGG) must be decoded to PCM first. Typical workflow: use a decoder library (libmpg123, libvorbis, FFmpeg/libav) to get raw PCM, then feed that PCM to an audio output API (SDL, PortAudio, OpenAL, etc.). For low-latency or real-time mixing, prefer a streaming API (PortAudio/OpenAL) rather than repeatedly spawning external players.

Troubleshooting tips: make sure sample rate, channel count and sample format exactly match the audio device settings; keep the program running until buffers drain; link the correct development libraries and include paths; on failure inspect return codes and check for format support. For quick testing the external-player approach works, but for games, GUIs, or anything requiring timing and control, decode+audio-device is the correct path.

You can try system function.

is one way to do it. If you google for "play sound" you will find other ways.

It basically depends on the kind of feat you are trying to achieve. Well if you want to go for normal playing of audio files you can try the above methods. But if you want to manipulate the sound stream like in games you can try out the open source sound libraries out there like "Bass" and "Audiere". Just google for them and you would be a happy man.

Hope it helped, bye.
