I found the cause of the problem (but not the solution). pulseaudio is trying to load the plugin before setting up the sound cards sink. The plugin obviously cannot find the sink for the sound card and fails. (It finds the auto_null sink and causes feedback loop error/issues). How do I force pulseaudio to load the hardware sound card sink before the plugin sink?! Here is my updated settings: [CODE] # This doesn't seem to do anything or force it to be loaded first set-default-sink alsa_output.pci-0000_00_1f.3.analog-stereo ## load ladspa module # The sink_master parameter doesn't seem to be forcing pulseaudio to load the soundcard sink first load-module module-ladspa-sink sink_name=compressor-stereo sink_master=alsa_output.pci-0000_00_1f.3.analog-stereo plugin=sc4_1882 label=sc4 control=1,1.5,401,-30,20,5,12 # set our custom compressor audio as default set-default-sink compressor-stereo [/CODE] Once I'm booted, if I kill pulseaudio, it restarts, and then it all works correctly! Very strange!
