unable to resolve SF::Sound (also SF::Music)

[Sapphira Tempest]

I have added require "crsfml" at the top of the file.

Need to require "crsfml/audio", that's probably what's missing

Thanks, it works.

But now another problem comes into being... xd

This is my code:

def play(audio : String,
         volume : Float64,
         loop? : Bool = false)
  if loop?
    music = SF::Music.new
    music.open_from_file audio
    music.volume = volume * 100
    music.loop = true
    music.play
  else 
    sound = SF::Sound.new SF::SoundBuffer.from_file audio
    sound.volume = volume * 100
    sound.play
  end
end

and here is the runtime error:

And no sound was played

It seems like to be a concurrent-related topic..
