Hmmm, module-equalizer-sink does not use LADSPA... or are you talking
about something else?

There is no generic interface to do this, so you have to unload and
reload the module. It wouldn't be too hard to write and interface to do
this but it would obviously take time.

What are you actually trying to achieve. The built in equalizer can
obviously be adjusted at runtime without reloading, but this is a
specific case due to a specific implementation of an equalizer and
nothing to do with LADSPA.
