Description

The currently implementation of WmfMedia player initialization is incorrect in that it creates a playback topology that includes all source tracks, but some of them are disabled. The intent was to enable/disable these tracks on the presentation descriptor on demand at run-time, but this is not supported by WMF. The topology must be re-created each time tracks are switched, and with only the active tracks contained in the topology.

Steps to Reproduce

1) Try to open a media file with multiple tracks, i.e. \\Z2448\Share\Media Files\Tests\Audio2Tracks.mp4

Note that the media fails to open with an error message about the presentation descriptor not being initialized correctly.
