I found this program I'd like to use: https://github.com/pulseaudio-equalizer-ladspa/equalizer I managed to compile and run it, but I don't hear it makes a difference in the sound. Do I need to enable the `module-ladspa-sink` module? Link: https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Modules/#module-ladspa-sink What makes it difficult for me to figure this out myself, is the [LADSPA](http://www.ladspa.org/) link, which seems to general, because this group develop many projects, or which I'm not sure which I should compile as a pulseaudio plugin (some of which are available in my distribution. Thanks for any help in advance.
