SetSystemVolume controls whether the jukebox volume control is
controlling the volume for the entire system via the hardware mixer
(True), or just controlling its own volume through software (False). The
default is False. It is not always possible to access the hardware mixer
on all sound cards; if you set this value to True and the volume does
not change when a volume key is pressed, the hardware mixer is not
accessible on your system.
Default value: False.

This value is interpreted as a percentage of the music volume.
Default value: 50.
SoundEffectsVolumeWhenPlaying sets the volume for sound effects that
start while a song is playing, from 0 to 100. This value is interpreted
as a percentage of the music volume.
Default value: 0.
Volume sets the initial music volume, from 0 to 100.
Default value: 100.
VolumeIncrement sets the amount the volume changes each time a
volume up/volume down key is pressed.
Default value: 10.
