Gets the number of audio streams available in the current media file.
Assembly: System.Windows (in System.Windows.dll)
Dependency property identifier field: AudioStreamCountProperty
The property value is valid only after the MediaOpened event has been raised.

If you were to examine the actual media, the audio streams might be interleaved with non-audio stream types, but these other streams will not be part of the collection.
