Summary: Csound5.13.0 noise when using JackoAudioOut

Initial Comment:
Hello.

When using the JackoAudioOut opcode to connect to another jack program, the csound output is just a very annoying noise.

I've found the problem in the file "jacko.cpp"

[...]
struct JackoAudioOut : public OpcodeBase
{
[...]
  int audio(CSOUND *csound)
  {
    jack_default_audio_sample_t *buffer = (jack_default_audio_sample_t *)jack_port_get_buffer(csoundPort, csoundFramesPerTick);
    for (size_t frame = 0; frame < csoundFramesPerTick; ++frame) {
      buffer[frame] += asignal[frame]; // <--- THIS IS THE PROBLEM!!!
[...]

>From what I've seen, the problem is in the line:
buffer[frame] += asignal[frame];

It's adding the new frames to the old ones instead of replacing them. The correct line should be:
buffer[frame] = asignal[frame];

I have recompiled it by using that fix and it works, no more noise and the correct sound output! :-))

I hope this is useful. Best regards!!

David Bluecame.
