Source
The two data fields "Source" and "MixerSource" are not independent. With this parameter you can specify a source which is set, if the user changes the mixer source of an element to one of the mixer sources. For example, for a mixer source called "CD", it would be useful to set the source to CD, too. This parameter is also used when TurboPlayer creates a new "spontaneous" element.
