Title: [SOLVED] No Sound in Terminal
Post by: Babbzzz on January 18, 2015, 05:36:34 am

This is my first program using SFML. I am unable to get any sound output.

#include <SFML/Audio.hpp>

int main()
{
    sf::SoundBuffer buffer;
    if (!buffer.loadFromFile("left.wav"))
        return -1;
    sf::Sound sound;
    sound.setBuffer(buffer);
    sound.play();
    return 0;
}

The program compiles and runs without errors but there is no sound. What seems to be the problem?

The program terminates just after calling play() so you never have time to hear the sound.
You need an event loop.

Thank you. After a little bit of research, I got it working using the below code.

#include <SFML/Audio.hpp>
#include <iostream>

using namespace std;
using namespace sf;

void playSound()
{
    // Load a sound buffer from a wav file
    SoundBuffer Buffer;
    if (!Buffer.loadFromFile("left.wav"))
        cout << "ERROR!" << endl;
    // Create a sound instance and play it
    Sound Sound(Buffer);
    Sound.play();

    // Loop while the sound is playing
    while (Sound.getStatus() == sf::Sound::Playing)
    {
        // Leave some CPU time for other processes
        sf::Time t1 = sf::seconds(0.1f);
        sf::sleep(t1);

        // Display the playing position
        cout << "\rPlaying... " << endl;
    }
}
int main()
{
    playSound();
    cout << "Done" << endl;
    return EXIT_SUCCESS;
}
