Good to know; I was trying to use gst-launch for my test app, but I
couldn't figure out how to filter the link between audioconvert and
audio/x-raw-float. I didn't realize that you could specify the format
directly in the pipeline.

Brilliant! It took me a while to figure out how to build and link
from CVS; but it's working for me now. My test app will compile and
run on my host machine; now I just need to cross-compile it to PPC and
ARM.
