Playing multiple audio files with Phonon

Hi,

we would like our application to play multiple audio files at once. http://doc.qt.nokia.com/4.7/phonon-overview.html states: "Currently, the multimedia framework supports one input source. It will be possible to include several sources. This is useful in, for example, audio mixer applications where several audio sources can be sent, processed and output as a single audio stream."

Does this mean that a single graph may not have more than one input source but that we may instantiate multiple graphs to have multiple input files played at the same time (and have them mixed by the kernel)? We will be using Windows if this is of any importance.

Cheers,
Martin
