Urgent: Need help regarding ecasound-mixing: Re: [ecasound] MIDI controllers...

Hi,
   This isn't related to the subject matter discussed in this mail.
However I was looking for someone who knows about the ecasound package.
I desperately need to make it work for one of my projects.
What I am looking for is to have my recording and want to add a
background that is coming from a small file that can go in a loop.

I just want to take that and mix the loop file in the background
so that it repeats for the entire duration of my recording.

Here is my short description of the problem. I will highly appreciate
if you can suggest me command line for ecasound to make it work.

Assuming I have a small 20s long audio file(f_small.wav) and a 10 minutes long audio file
(f_long.wav).
I want to mix them in such a way that the f_small.wav repeats (loops) in the background for the
entire duration of f_long.wav (10 min).

How to make it work.

I used
../ecasound -a:1 -i f_long.wav -a:2 -i f_small.wav -tl -a:all -o mixed_new.wav

It just waits and never finishes:

What am I doing wrong.
