Actually this is a completely valid sequence of EIAM commands.
Have you checked whether 'cs-connect' succeeds? I created a similar setup
replacing 01follow_me.mp3 with my good ol' foo.wav and it worked (w/
2.1dev-cvs).
One thing to check is that there are no other chains than 't1'. It's not
legal to have a chain that has no input and/or no output. In other words,
all chains of the chainsetup-to-be-connected must be valid. On the other
hand, it _is_ legal to have inputs/outputs that are not connected to any
chains (like is the case in your example above).

That sounds reasonable.
