And probably the least prolific with gr.
Which is one reason why I'm a bit reluctant to work on this.
Another one is the way gr is written. I'm used to C++, python,
and writing C/C++ extensions for Python. But I usually stay
well clear from things like boost and swig (and python2).
Is there any way to create an audio sink out-of-tree and
use it with a binary install ?
Looking at jack_sink.cc I find in work():
work_size = noutput_items * sizeof(sample_t);
while (work_size > 0)
{
// write some data to a queue
work_size -= write_size;
}
Why would a sink (which doesn't output anything to another
gr module) ever use the 'noutput_items' argument to work() ?

A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
