Hello,
I'm trying to find out why portaudio doesn't work with my windows machine.
pd doesn't stuck anymore if I put Pa_Terminate() at the end of function "static void pa_init(void)" in s_audio_pa.c
I don't understand why Pa_Terminate() is not used anymore, it's under comments in function int pa_open_audio()
because by reading http://portaudio.com/docs/v19-doxydocs/initializing_portaudio.html, I see that this function must be used.
It doesn't matter anymore because I've partly resolved the problem, and it partly comes from portaudio...
If pa_process.c has been modified like explained in following link:
http://music.columbia.edu/pipermail/portaudio/2012-December/014649.html
audioindev audiooutdev can be forced before declaring asio like this:
pd -audioindev 13 -audiooutdev 12 -asio
Then It's possible to know which device to use with this command:
pd -audioindev 0 -audiooutdev 0 -asio -listdev
I hope someone can rewrite PaError pa_open_callback(...) in s_audio_pa.c because all those problems mainly comes from this function, and asio will certainly work better for everyone. My guess would be about making sure that p_instreamparams and p_outstreamparams aren't NULL before starting pa_stream.
cheers,

Hi Patrice -
I actually don't have any working ASIO devices which makes it hard for me to figure out what's wrong here. I'll make another attemot to get something installed in the next week or so. Meanwhile, am I reading this right that you get different results depending on whether you put the -asio flag before or after the " -audioindev 13 -audiooutdev 12" ? I don't know why that would happen.
cheers Miller

Hello Miller,
When pd is started from msys console with asio flag after audioindev and audiooutdev, msys console show this:
///Assertion failed: //!bp->host(In|Out)__putIsInterleaved, //file src/common/pa_process.c, line 498/
I don't know implications of removing those 'assert()' lines from /pa_process.c/, but it's the only solution I've found out to have asio devices working again with versions of PureData using the new portaudio interface.
Also, I forgot to mention that pd doesn't crash when selecting asio if callback toggle is enabled, but it's extremely slow.
I'll try to package a version with the code modification maybe this week to see what's happening on other computers,
cheers,
PatCo
