Hi m (?), this looks like a problem caused by the pipe communication which I still have to debug. It happens when an Ecasound command lasts too long. The simplest solution is to 'hide' your LADSPA plugins from Ecasound, i. e. unset LADSPA_PATH and comment out the ladspa-plugin-directory = xxx line in ~/.ecasound/ecasoundrc. But this will also mean that you can't make use of your LADSPA plugins using Visecas/Ecasound, which is a pitty. So you could do me a favour and edit lib/visecas/ecasound.rb by hand instead. Increase the TIMEOUT constant (line 76) and try if that changes your situation. And just to be sure: Does echo "map-ladspa-list" | ecasound -c list your LADSPA plugins? I had similar problems before. For me they are fixed now ;) but this timeout thing depends on your system.
