We are very close with the portaudio but not quite there with the stuff
but what I am seeing says to me this is going to be a real winner. We
are having the usual ring buffer and other simple arithmetic problems.
Stephane made a good start doing 85% of the logical work and 100% of the
grunt work in that he built almost all of the required portaudio API
glue. For those experimenting with portaudio please use pa_mono_tone.py
and pa_multi_tone.py. You will see that mono_tone.py and multi_tone.py
have been returned to their original ALSA only condition. The only
work happening at the moment is on the sink code. Eric has kindly
modified omnithreads to give us a binary semaphore that should be
reasonably spiffy on Windows, OSX, and Linux since (for example) Windows
does not do futexes, etc.
Right now, audio_portaudio_sink.py has GABBY_DEBUG defined. You will
see lots of output as a result. The reason for this is to aid us in
parsing what portaudio gets back from its interrogation of the hosts. I
ran the code with some glitches on many different hosts today.
That sink code is not yet fully functional but we are close. Once the
sink is sorted out, the source will be next.
