What's the best method to access to soundcard info and number of channels from a PD patch?

I try to explain... I'm comunicating PD patch with Flash using OSC. How can I retry soundcard type, info, and number of channels from the PD patch and send to Flash app?

Thanks a lot in advance.

Excuse me for my insistence. I can't find the way to access to soundcard info and number of channels from a patch and send it to external application using OSC messages. I don't want to use Media Menu-> Audio Settings.

All comments will be welcome. Thanks in advance.

why not?

Ok, I try to explain.
I want to run PD patch as a windows service (no visible). All the interaction with PD is performed by a Flash interface using OSC. For this reason, I want to access to soundcard settings in other way. Do you understand?

Maybe it's a "stupid" setting. I know. But I want to try it.

thanks.

I asked on the list for you because this isn't something that Pd can do by default. Tim B replied that he wrote something, an object that can do it. You would have to find this and compile it, I'm just passing back the reply for you......

a few years ago, i implemented a message-based access to pd's audio
backend ...
possibly the patch is still somewhere around ... maybe you can still find
it on the sf patch tracker?

hth, tim

samplerate~ of course is easy, but for the other things I don't know
an elegant solution. This is especially hard as Pd uses so many
different ways to access a sound device: Portaudio, ALSA, OSS, JACK,
ASIO, Coraudio, maybe more?

You could try to eavesdrop on the [r pd] receiver, watch for
audio-related messages:

print: audio-setapi 1
print: audio-dialog 0 0 0 0 2 0 0 0 0 0 0 0 2 0 0 0 44100 50
print: audio-setapi 2
print: audio-dialog 0 0 0 0 2 0 0 0 0 0 0 0 2 0 0 0 44100 50

but that only works for changes to a running patch.

Thanks Obiwannabe,
it seems no easy to implement.
At this moment I only need it works with ASIO.

I'll be waiting for news.

This may be silly but, wouldn't the soundcard 'settings' be available system-wide? Couldn't you just stick to a standard implementation throughout your patches, and then just hard code it on both ends? If you mean to switch soundcards, couldn't Flash 'go and get' the ASIO info all on it's own?

Ok Nestor. Maybe you are right. I will try to get soundcard info from Flash.
I will tell results.

Thanks.

I have no success using Flash to detect soundcard.

I will continue trying in PD. I think if PD can show soundcard info in Media menu it must be possible to do from a patch. It seems logical,or not?

Your ideas will be welcome.
