Browse source 
Original commit message from CVS:
* gst/wavparse/gstwavparse.c: (gst_wavparse_stream_headers):
Pass extra_data to gst_riff_create_audio_caps(), so that
WAVEFORMATEX stuff works. Post audio codec name and post
it as taglist on the bus. Allow up to 8 channesl for raw
PCM in the source pad template caps.
