Hi, Thanks for the patch review! Here are the revised patches. I agree that the interface is quite limited for GUI use, and is mostly useful when the plugins are known beforehand. However, to do complex LADSPA plugin management, the GUI needs to dig quite deeply to the PulseAudio internals -- think having multiple LADSPA plugins chained together. The hypothetical GUI application might do the plugin introspection directly from the plugin files like the "analyseplugin" command does. -- Ismo Puustinen <ismo.puustinen at intel.com>
