I am trying to make a small program that plays a sound whenever a key is pressed. I am mostly doing this to learn SFML and get better at cpp.

Looking at similar problems I have both the sf::SoundBuffer and sf::Sound as standalone members in a game class. The code works enough that the keystrokes are being registered (tested them by having them just close the window) but it refuses to play any sound. I have double checked the location of the sound files I am calling and it checks out. Any help would be greatly appreciated!

below is how I am loading the audio and the keypresses

void Game::loadSound(sf::SoundBuffer buff, sf::Sound sound, std::string file)
{
    buff.loadFromFile(file);
    sound.setBuffer(buff);
    sound.setVolume(50);
}

void Game::initSounds()
{
    loadSound(buffer1, drum1, "../sounds/Drum1.wav");
    loadSound(buffer2, drum2, "../sounds/Drum2.wav");
    loadSound(buffer3, drum3, "../sounds/Drum3.wav");
    loadSound(buffer4, drum4, "../sounds/Drum4.wav");
    loadSound(buffer5, spock, "../sounds/Spock.wav");
    loadSound(buffer6, spike, "../sounds/Spike.wav");
}

void Game::pollEvents()
{
    //Event Polling
    while (this->window->pollEvent(this->event))
    {
        switch(this->event.type)
        {
        case sf::Event::Closed:
            this->window->close();
            break;
        case sf::Event::KeyPressed:
            switch(this->event.key.code)
            {
                case sf::Keyboard::Escape:
                    this->window->close();
                    break;
                case sf::Keyboard::Num1:
                    drum1.play();
                    break;
                case sf::Keyboard::Num2:
                    drum2.play();
                    break;
                case sf::Keyboard::Num3:
                    drum3.play();
                    break;
                case sf::Keyboard::Num4:
                    this->drum4.play();
                    break;
                case sf::Keyboard::Num0:
                    this->spike.play();
                    break;
                case sf::Keyboard::Num9:
                    this->spock.play();
                    break;
            }
            // if(event.key.code == sf::Keyboard::Escape)
            //     this->window->close();
            break;
        }
    }
}
