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
Increase the TIMEOUT constant (line 76) and try if that changes your

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

I hope this helps,
