I'm experimenting with getting the csound API to play happily with jack, and am having a strange error.

If my test app has the following:

int result = cs->Compile(argc, argv);

And I call it with:

./csoundAPItest -+rtaudio=jack -odac -b64 -B128 monosynth5.orc monosynth5.sco

it works fine and audio goes out over jack. But if I have this:

char *csArgs[6] = {"-+rtaudio=jack", "-odac", "-b64", "-B128", "monosynth5.orc", "monosynth5.sco"};
int result = cs->Compile( 6, csArgs);

It doesn't use jack and tries to play it with Portaudio ( which I don't even have installed ), terminal session below.

Anyone have any clue why?

Thanks

Iain
