This will output the sound coming from a positionable audio source.
This gives you slightly more control over the sound playback compared
to the other playSound methods. For example, if you would like to
stop the sound prematurely you can call this method with a
TransportAudioSource and then call audioSource->stop. Note that,
you must call audioSource->start to start the playback, if your
audioSource is a TransportAudioSource.
The audio device manager will not hold any references to this audio
source once the audio source has stopped playing for any reason,
for example when the sound has finished playing or when you have
called audioSource->stop. Therefore, calling audioSource->start() on
a finished audioSource will not restart the sound again. If this is
desired simply call playSound with the same audioSource again.
@param audioSource the audio source to play
@param deleteWhenFinished If this is true then the audio source will
be deleted once the device manager has finished
playing.
@param sampleRateOfSource The sample rate of the source. If this is zero, JUCE
will assume that the sample rate is the same as the
audio output device.

than buffer channels, then the ones that are available will be re-used on
