GStreamer 0.8.7? From October 2004? Are you serious?

I'm fairly sure what you want to do is doable even with such an old
version. However, not only is that version more than five years old, but
we've also had a major API/ABI change since then, so don't be surprised
if no one remembers anything at all about 0.8.x.

If all you want to do is write raw audio PCM data to disk as a .wav
file, something like libsndfile might be a better fit. I wouldn't
recommend using an ancient and unsupported GStreamer version.
