creates the object and returns a pointer to it. TODO: The wavein and midiout components should also move to separate classes. When finished, it should be possible to configure the sound support more detailed (e.g. waveout with sdl, midiout with alsa and the dummy driver for wavein). Creating a separate module for the output to file(s) is also possible.
