Hello all1
   I'm using csound 5.13.0 under Linux. There seems to be a problem with 
dssi4cs and jack output. I have an instrument with an oscillator from a ladspa 
plugin. Without that plugin - using a simple oscil instead - everything is 
fine. Using that plugin (Fons Adriaensons blvco.so (1953, sawtooth), the 
following happens.
   The moment I connect one of csounds ports to a playback port on my 
soundcard, that port is silent. the moment the connection is broken, it comes 
back to life.
   If you need the complete instrument, just tell me.
   Question: What could that be? How can csound block my audio output like 
this? - Oh short thought: I'm using all the defaults and for exp_fm, lin_fm 
and sync I use 0.
   Kindly yours
            Julien

Which version of Linux are you using?
More specifically, is it one that rests on pulseaudio?

Hello Samuel!
   I'm using Debian Lenny, with self compiled vnilla 2.6.30.4 kernel. Built-in 
ALSA (1.0.20) and running directly ontop of that jackdmp (1.9.7), also self 
compiled. and I'm very sure, there's nothing more audio wise. I'm using a 
completely text based system, for being blind and the system being VERY fast 
that way. and I have taken care of compiling most of my audio software for 
about 11 years, so I suspect it can't be something major wrong there. 
Especially since I use a lot of other audi software without problems.
   but as I said, the problem only arose, when using the blvco plugin for an 
osciallator. Swap that for a simple oscil and everything is fine.
   Warmly yours
          Julien

Hi Julian,

Does that happen with other ladspa plugins, or just that one in particular?

Cheers,
Andres

Helly andres!
   I just noticed, not only with that one in particular, but with that one, in 
that instrument. I suppose I just include the instrument below and you can 
beat me up for all my shortcomings, in such a small orchestra. :-(
   Kindly yours
           Julien
