You're right about the launch line not working for channel-positions, 
fortunately this was going into a C app anyway.
I ended up fixing the issue by setting the channel-positions argument of 
interleave to the 8 channel layout specified in 
(other layouts may work as well, I'm not sure), kind of like the 2 
channel example from gst-plugins-bad/tests/check/elements/interleave.c
Thanks for your help, and thanks also to slomo for some earlier feedback 
on this issue.
