OS X Mavericks default audio input & output devices are "Airplay" instead of selected default device

QSound & QSoundEffect will not work correctly on OS X 10.9.1 because QAudioDeviceFactory::defaultOutputDevice() selects the first item on the list of available devices which on this version of OS X is NOT the default device.

e.g.:

qDebug() <<QAudioDeviceInfo::defaultOutputDevice().deviceName();

produces:

"AirPlay"
