SoundBuffer error "Incomplete type not allowed"

[Tristanbox09]

Hello guys,

I am trying to load a losing sound for minesweeper, and I achieved this in the main window first. I then moved my function to a class and I am getting an incomplete type not allowed on my buffer object. Any ideas? My code is below:

void Board::losingSound(sf::SoundBuffer& buffer, sf::Sound& sound)
{
   buffer.loadFromFile("sound/gameover.wav");


   sound.setBuffer(buffer);

   sound.play();

   soundOff = true;
}

what is soundOff?

Did you also move line

#include <SFML/Audio.hpp>

into your header?
