You need to link spider to fakesink using filtered caps.  This
tells spider that you actually want audio samples to go to the
fakesink.  Fakesink will accept anything, so spider doesn't bother
converting the input the stream to audio -- it will just send the
input stream to fakesink unchanged.

A good starting point would be something like:

  gst_element_link_filtered(spider,fakesink,
    GST_CAPS_NEW("filter_caps","audio/raw",NULL));
