Hi, I was looking into using the Csound API, using the example code from the FLOSS manual (http://write.flossmanuals.net/csound/a-the-csound-api/) and I've been getting an error where I'm getting no audio output. In the terminal I get the following message:

 unknown rtaudio module: 'PortAudio', using dummy module

rtaudio: dummy module enabled

Really unsure why this is happening, I'm on a mac so PortAudio should be the correct rtaudio module. I know my csd is running because I added a printks statement which succeeds in printing to the terminal. Tried selecting port audio both in my csd and in the command line. I've included all the code I am using, please let me know if you see anything. 

Here is my csd:

<CsoundSynthesizer>

<CsOptions>

-odac1 -+rtaudio=PortAudio

</CsOptions>

<CsInstruments>

sr = 44100

ksmps = 128

nchnls = 2

0dbfs = 1.0

turnon 1

instr 1

printks "i'm on", 1

a1 oscil .8, 440

outs a1, a1

endin

</CsInstruments>

<CsScore>

</CsScore>

</CsoundSynthesizer>

Here is the example code from the manual that I am running:

Run with command line ./apitest "csdfilename"

#include <stdio.h> 
#include <csound/csound.h> 

uintptr_t csThread(void *clientData); 

typedef struct { 
  int result; 
  CSOUND *csound; 
  int PERF_STATUS; 
} userData; 

int main(int argc, char *argv[]) 
{
  int finish;
  void *ThreadID; 
  userData *ud; 
  ud = (userData *)malloc(sizeof(userData));  
  MYFLT *pvalue; 
  ud->csound = csoundCreate(NULL);  
  ud->result = csoundCompile(ud->csound, argc, argv); 

  if (!ud->result) {  
    ud->PERF_STATUS = 1; 
    ThreadID = csoundCreateThread(csThread, (void *)ud); 
  } 
  else { 
    return 1; 
  }  

  /* keep performing until user types a number and presses enter */
  scanf("%d", &finish);
  ud->PERF_STATUS = 0; 
  csoundDestroy(ud->csound); 
  free(ud);  
  return 0; 
} 

/* performance thread function */
uintptr_t csThread(void *data) 
{ 
  userData *udata = (userData *)data; 
  if (!udata->result) {
    while ((csoundPerformKsmps(udata->csound) == 0) &&
           (udata->PERF_STATUS == 1));
    csoundDestroy(udata->csound); 
  }        
  udata->PERF_STATUS = 0;    
  return 1; 
}

You may need to set OPCODE6DIR64? I had similar issues on OSX recently. My app could find the Csound library but none of the auxiliary libs.

You don't need to set it in C. You can set it from the command line using 'export'.

Would I do that as part of the command line running my compiled c file or would I run it beforehand. Do you have an example command line?

You can try something like:

export OPCODE6DIR64="path to Csound opcodes"

Note that it will only be valid for the current session. Csound checks this environment variable on startup, if it is not there, Csound may not find certain plugin opcodes. I have to say at this stage that I've very little OSX experience! But i'm happy to throw out suggestions.

I just tried this, in the terminal I ran: 

export OPCODE6DIR64=/Library/Frameworks/CsoundLib64.framework/Versions/6.0/Resources/Opcodes64 

then

./apitest

I got the same result. Is the export command supposed to be something different between c and python perhaps?

Thank you everyone for their help. I really appreciate it.

You can try something like:

export OPCODE6DIR64="path to Csound opcodes"

Note that it will only be valid for the current session. Csound checks this environment variable on startup, if it is not there, Csound may not find certain plugin opcodes. I have to say at this stage that I've very little OSX experience! But i'm happy to throw out suggestions.

Would I do that as part of the command line running my compiled c file or would I run it beforehand. Do you have an example command line?

You don't need to set it in C. You can set it from the command line using 'export'.

How do I set the opcode directory in c? The only examples I can find of this are python.

You may need to set OPCODE6DIR64? I had similar issues on OSX recently. My app could find the Csound library but none of the auxiliary libs.

I have tried both of those actually, I added the -+rtaudio=portaudio after I was getting no output with just -odac in the header. I tried both capitalized and non capitalized just to make sure. PortAudio is the name they give in the csound command line flags page so I was a little confused.

you probably mean "OPCODE6DIR64" ?

difference. 

John, where is that setenv command used? In the terminal before running?

That was an answer to how to do it it C, so anywhere before calling any csound API.

If you are getting references to PortAudio it tells me that you are not on Linuxfor which alsa is the default, ( As an aside I think this is a bug in bsd and oter un*x style fiing systems that are case sensitive)

Do you have any file with names like librt*?  I have portaudio as librtpa.so -- but I am not the correct person to help, being 100% Linux site (and an unused Windows XP machine)

Just my 2c on this, it might be unrelated, but when I tested the new
installer for windows I got the same kind of problem. I turns out, for
me it was related to several different Csound versions residing in my
system. The Csound library included with Cabbage was found before the
canonical one, and there were differences in how to access reatime
audio and midi between those two versions.
Just as a test, could you try running something with rt audio in
Csound from the command line? This will confirm that your installed
Csound can communicate with the audio device. Then, take a note of the
Csound version number and build date (of this Csound version that you
run in the terminal). Then when you run your program using the
csoundAPI, check that the version number and build date is identical
to what you got with command line Csound. If there is a difference,
that might well be the source of the problem. If not, then this tip
did not matter for your situation.
