What distro of Linux are you running?

Eyeballing the Arch package for this equalizer, it looks like it needs
the swh-plugins package for the actual LADSPA plugin itself. It might be
named differently on your distro.

You shouldn't need to manually load any modules in pulse; this equalizer
script seems to do all the module loading automagically.
