Loading module-ladspa-sink with the parameters that you use resulted in the following: D: [pulseaudio] module-ladspa-sink.c: Module: lowpass_iir_1891 D: [pulseaudio] module-ladspa-sink.c: Label: lowpass_iir D: [pulseaudio] module-ladspa-sink.c: Unique ID: 1891 D: [pulseaudio] module-ladspa-sink.c: Name: Glame Lowpass Filter D: [pulseaudio] module-ladspa-sink.c: Maker: Alexander Ehlert <mag at glame.de> D: [pulseaudio] module-ladspa-sink.c: Copyright: GPL D: [pulseaudio] module-ladspa-sink.c: Port 0 is control: Cutoff Frequency D: [pulseaudio] module-ladspa-sink.c: Port 1 is control: Stages(2 poles per stage) D: [pulseaudio] module-ladspa-sink.c: Port 2 is input: Input D: [pulseaudio] module-ladspa-sink.c: Port 3 is output: Output D: [pulseaudio] module-ladspa-sink.c: Will run 2 plugin instances D: [pulseaudio] module-ladspa-sink.c: Trying to read 2 control values D: [pulseaudio] module-ladspa-sink.c: cdata: '110,0.755' D: [pulseaudio] module-ladspa-sink.c: Read config value 110.000000 (p=0) D: [pulseaudio] module-ladspa-sink.c: Read config value 0.755000 (p=1) W: [pulseaudio] module-ladspa-sink.c: Control value 1 below lower bound: 0.755000 (lower bound: 1.000000) E: [pulseaudio] module-ladspa-sink.c: Failed to parse, validate or set control parameters Segmentation fault So, the parameter for "Stages" seems to be invalid, and that then triggers some bug in pulseaudio. -- Tanu
