So there's no way at the moment to make pulseaudio work with any
ladspa plugin? There are other pulgins provided by ladspa doing
something similar, one is called plate_1423, another C* Plate...
There also are lots of people on the internet saying they are able to
use a ladspa equalizer (it didn't work for me).
