I don't think it is...

Sorry, I made a mistake: you need to connect the *outputs*
of jconvolver to the soundcard, i.e. add the soundcard
ports to the /output/name lines.

> 3/ Start squeezelite : squeezelite-arm -o jack

This will probably connect directly to the soundcard,
not to jconvolver. So you get sound, but without the
convolution.

What you can do is:

Add the connections from squeezelite to jconvolver to
the config file (on the /input/name lines). Then 
    
   - start squeezelite,
   - disconnect it from the soundcard using jack_disconnect
     with the correct port names,  
   - start jconvolver, this will make all connections.

This assumes that squeezelite does not need to be
restarted for each track.
