According to the header file the outputVolume properties supported range is 0.0-1.0:


/*! @property outputVolume
	@abstract The mixer's output volume.
	@discussion
		This accesses the mixer's output volume (0.0-1.0, inclusive).

@property (nonatomic) float outputVolume;

However when setting the volume to 2.0 the audio does indeed play louder. Is the header file out of date and if so, what is the supported range for outputVolume?

Thanks
