I don't think changing the flow graph buffering is going to make any

high-functioning audio sink/source using portaudio.  It's on my list,
but if somebody else wants to do it, please do (talk to me.  I've got
some ideas.)  Using the portaudio CVS version 19 stuff, there is now good
support for windows, and under ALSA and jack under Linux.  It's also
supposed to work under OS/X using CoreAudio.
There hasn't been any official releases since the 30 June 2003 with V18.1. Do you think its a good idea to use the CVS version?

No releases usually means an unacceptable status of the current work unfit for public release.

Could be.  On the other hand it appears that good work is being done
in CVS.  Lots of activity on their mailing lists.  Not sure why they
haven't made a release yet.  The V18.1 stuff will not solve our
problem, so I see zero reason to even consider it.  I'm hoping to
handle *all* audio issues on *all* platforms with a single
gr-audio-portaudio module.  [ I could be dreaming, but hey, that's what
portaudio is supposed to do ;) ]

If we find that their CVS works for us on all platforms we care about,
then we talk to the developers and see what it would take to get them
to make a V19 official release.  Perhaps nobody's asked them in a few
years ;)


This would seem to be a pretty straightforward as they do maintain a "to-do" list however, the to-do list seems out of date the last time I looked. All I can tell you is what my experience has been and what I have been observing over the past year. PortAudio appears to be taking off after it really languished in a very quiet period (as Berndt has correctly pointed out) for almost a year without major forward motion. Then Arve and Eric W got things rolling again. The traffic level is constant with a few developer messages a day on the portaudio list.
