Hmm, could jconvolver be needing the JACK server name?

Usage: jconvolver <options> <config file> {<connect file>}
Options:
   -h                 Display this text
   -v                 Print partition list to stdout [off]
   -L <nframes>       Try to compensate <nframes> latency
   -M                 Use the FFTW_MEASURE option [off]
   -V                 Use vector mode processing [off]
   -N <name>          Name to use as JACK client [jconvolver]
   -s <server>        Jack server name

As I stated in the OP

"I also tried to run jconvolver -sjackd / jconvolver -sjackdbus but also without success."

Also tried 
jconvolver -sjackdmp 
jconvolver -sdefault

I think if you don't use the option -s jconvolver should use to the default server name.

Thanks

Moshe
