Please think for a second. It doesn't make any sense to connect an input to an input. You always need jack_connect some_output some_input For example jack_connect jconvolver:out.L system:playback_1 jack_connect jconvolver:out.R system:playback_2 Note that the system:playback ports are *inputs*, even if they correspond to the outputs of the sound card. Think of these ports as the inputs of the D/A converters. > #/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 This is OK. > 1/ start jack2 : jackd -d alsa -r 44100 -p 256 -n 16 -P -S Try -p 256 -n 2, or -p 512 -n 2.

Try this: 1. Start jack (with -p 256 -n 2). 2. Start squeezelight. 3. Use jack_lsp -c to see the ports and the connections. Probably squeezelight has connected to the playback ports, and you have sound. If that is the case, use jack_disconnect to disconnect squeezelight (2x). Verify again with jack_lsp -c. There must be no connections. 4. Start jconvolver. 5. Use jack_connect to connect squeezelight to jconvolver:in (2x). 6. Use jack_connect to connect jconvolver:out to the soundcard (2x). If all of this works, you can put the connections in the jconvolver config file. Then if you start jconvolver last it will make all the required connections. *** But then you still need to remove the direct connections *** from squeezelight to the soundcard. If you don't, you get *** a mix of the sound with convolution and without, and that *** will not sound right. -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
