Hello,
I'm tryng to make jconvolver to work on Pi B (for a Pi Zero setup when it
will be available to me)

I had a setup working fine with Pi 2 and Pi 3

I did a fresh MINIMAL install on Pi B
Jackd is running but each time I try to start jconvolver I get an error :
Illegal instruction

Here is my asound.conf
# Send both CHANNELS alsa API to jconvolver
pcm.rawjack {
    type jack
    playback_ports {
        0 jconvolver:in.L
        1 jconvolver:in.R
        }
    capture_ports {
        0 system:out_L
        1 system:out_R
        }
}
# jackplug
pcm.jack {
    type plug
    slave { pcm "rawjack" }
    hint {
  description "JACK Audio Connection Kit"
    }
}
# use following peripherical by defaut with alsa:
pcm.!default {
    type plug
    slave { pcm "rawjack" }
}

Here is my Filter.conf
  GNU nano 2.2.6 File: filter-44100.conf

# in out partition maxsize
# ---------------------------------------------------------------
/convolver/new 2 2 1024 65536

# num port name connect to
# -----------------------------------------------
/input/name 1 in.L rawjack:out_000
/input/name 2 in.R rawjack:out_001
#
/output/name 1 out.L system:playback_1
/output/name 2 out.R system:playback_2
#

# in out gain delay offset length chan file
# --------------------------------------------------------------------------
/impulse/read 1 1 0.85 0 0 0 1 highpass_44.wav
/impulse/read 2 2 0.85 0 0 0 1 highpass_44.wav
#

Then :
*STEP 1 (OK)*
root@email-addr-hidden:~# jackd -d alsa -d hw:Audio -r 44100 -p 256 -n 2 -P -s

*STEP 2*
root@email-addr-hidden:~/jconv/filter# jconvolver filter-44100.conf
Illegal instruction

Any Idea of what is wrong here ?
