new SoundEffect "System.NotImplementedException" The method or operation is not implemented.

SoundEffect sound;
byte[] b = …;

So this simple method is works fine:
sound = new SoundEffect(b, 44000, AudioChannels.Stereo);

But if im creating the completly method, something like this:
sound = new SoundEffect(b, 0, b.Length, 44000, AudioChannels.Stereo, 0, b.Length);

I am getting an exception message. So this expanded method is not implemented into MonoGame?
