Jconvolver on Raspberry Pi B / PI Zero - Linux-audio-user

26 May 2016

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)*

Any Idea of what is wrong here ?
