I've tried to convert multi-channel audio files with SoundConverter, and it
wasn't able to handle them. So I created a minimal command to reproduce the
problem: 
gst-launch filesrc location=8Ch_Wind_8sek_test04.wav ! decodebin ! audioconvert
! wavenc ! filesink location=test8ch.wav

Which gives me the following message:
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

** (gst-launch-0.10:3728): WARNING **: Failed to retrieve channel layout from
caps. This usually means there is a GStreamer element that does not implement
multichannel audio correctly. Please file a bug.

Done :)

In fact, audiorate and audioresample seem to have the same problem.
