You are right I first thought you made a mistake and had tried to connect the *outputs* of jconvolver to the soundcard, i.e. add the soundcard ports to the /output/name lines. But didn't got sound. than Idid what you said connect the *intputs* of jconvolver to the soundcard, i.e. add the soundcard ports to the /intput/name lines. and got sound, but after listening to a known track, I understood that it was not convoluted. So what i just did, and now it looks like working. I changed again filter-44100.conf, this way : /# 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 #/ Than, 1/ start jack2 : jackd -d alsa -r 44100 -p 256 -n 16 -P -S 2/ start jconvolver : jconvolver filter-44100.conf 3/ jack_disconnect system:playback_1 jconvolver:out.L -> OK 4/ jack_disconnect system:playback_2 jconvolver:out.R -> cannot disconnect client, already disconnected? 5/ start squeezelite : squeezelite-arm -o jack I have sound and quite sure it is convoluted, i'm a little bit lost in all this ! What do you think ? Best regards and thank you for helping me.
