Hello world, sorry for my last blank message.. Maybe I have some problems with my e-mail client. Anyway, I've recently installed pulseaudio-0.9.15 for the first time on my Debian Sid kernel 2.6.30-1-amd64 and I'm very satisfied of it :). I'm now trying to set a reverb through pulseaudio on gnome's rhythmbox. According to Aqualung (on which it is working fine) there's a Ladspa plugin in "/usr/lib/ladspa/caps.so" labeled Plate2x2 that should make what I want. I added this line to my ~/.pulse/default.pa "load-module module-ladspa-sink sink_name=ladspa_out master=alsa_output.pci_10de_59_sound_card_0 plugin=caps label=Plate2x2 control=0.700,0.400,0.300,0.500" But when I try to start pulseaudio it fails: E: module-ladspa-sink.c: Found audio input port on plugin we cannot handle: in:l E: module.c: Failed to load module "module-ladspa-sink" (argument: "sink_name=ladspa_out master=alsa_output.pci_10de_59_sound_card_0 plugin=caps label=Plate2x2 control=0.700,0.400,0.300,0.500"): initialization failed. E: main.c: Module load failed. E: main.c: Inizializzazione del demone non riuscita Then, pulseaudio does not start. Is there something I'm wrong or, of course.. is there an alternative solution?
