I think what you are describing is clear. However I think (I'm a total 
noob with gstreamer just FYI) that the confusion is that gstreamer 
abstracts the hardware away. You don't deal with the low level details 
you are describing. functions like waveOutOpen and such would be within 
a gstreamer plugin for writing to a wave device in windows. However 
gstreamer is intended to be used by apps...and not directly talk to any 
hardware.
