[LAU] Jconvolver on Raspberry Pi

[bricolodu]

Hello,

Thank you i saw my mistakes.

However, although I have no more errors, I still have no sound from
squeezelite and from mplayer , I have the feeling it is not passing through
jconvolver.

here are my config files :
*asound.conf :*
*# convert alsa API to jack API*
*# use it with:*
*# % aplay foo.wav*
*# pcm type jack*
*pcm.rawjack {*
*    type jack*
*    playback_ports {*
*        0 jconvolver:in.L*
*        1 jconvolver:in.R*
*        }*
*    capture_ports {*
*        0 system:Output_L*
*        1 system:Output_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" }*
*}*

*filter-44100.conf :*
*# Replace by whatever required...*
*#*
*#/cd /root/folve/filter*
*#*
*#                 in out    partition      maxsize*
*# ---------------------------------------------------------------*
*/convolver/new    2    2        1024        65536*
*#*
*#*
*#              num   port name     connect to*
*# -----------------------------------------------*
*/input/name     1     in.L*
*/input/name     2     in.R*
*#*
*/output/name    1     out.L*
*/output/name    2     out.R*
*#*
*#*
*#               in out gain delay offset length  chan    file*
*#
--------------------------------------------------------------------------*
*/impulse/read   1  1  0.75    0      0       0    1
 T-Monacor_SPH30X.wav*
*/impulse/read   2  2  0.75    0      0       0    1
 T-Monacor_SPH30X.wav*
*#*

*Procedure :*
1/ start jack2
2/ start jconvolver
3/ start mplayer or squeezelite

mplayer seems to connect to jack directly
I thought I could indicate to connect to jconvolver

*if I run : squeezelite-arm -l *
*I get :*
*Output devices:*
*  null                           - Discard all samples (playback) or
generate zero samples (capture)*
*  pulse                          - PulseAudio Sound Server*
*  rawjack*
*  jack                           - JACK Audio Connection Kit*
*  default*
*  sysdefault:CARD=sndrpihifiberry - snd_rpi_hifiberry_dac,  - Default
Audio Device*
*  dmix:CARD=sndrpihifiberry,DEV=0 - snd_rpi_hifiberry_dac,  - Direct
sample mixing device*
*  dsnoop:CARD=sndrpihifiberry,DEV=0 - snd_rpi_hifiberry_dac,  - Direct
sample snooping device*
*  hw:CARD=sndrpihifiberry,DEV=0  - snd_rpi_hifiberry_dac,  - Direct
hardware device without any conversions*
*  plughw:CARD=sndrpihifiberry,DEV=0 - snd_rpi_hifiberry_dac,  - Hardware
device with all software conversions*

if I try to play music with squeezelite, evrything seems to work but I get
no sound.

Best Regards,
Jean
