Also, do you mean that the default output works without 1/3 second
distortion?  Or, the distortion happens regardless of your PCM device
setup?

I'd like to concentrate on debugging the default setup at first,
so better to reduce the risk of brokenness of ladspa plugin.
If you get any severe problems with the default setup, please let me
know more details.
