Hi i am makeing a little alarm clock and want to add a wav sound I done the code below but there is no sound when i use the code the wave file is also in the correct place any idea what i am doing wrong thanks.

Code:
            string sFile = Path.Combine(Application.StartupPath, "attention.wav");

            if (File.Exists(sFile))
            {
                System.Media.SoundPlayer sp = new SoundPlayer();
                sp.SoundLocation = sFile;
                sp.Play();
            }
