[PD-dev] The ins and outs of ins and outs...

[Ryan Gallagher]

Hi again...

Well, you all read the latest CVS corrects my slow
mouse input woes (bravo!).  Now perhaps some kind soul
could elucidate the method of specifying correct audio
device numbers at startup. The current OS X info in
the online manual (sec. 3.4) is somewhat outdated. 
Btw, I'd be happy to contribute documentation to help
ease other novice OSX users getting started (once I'm
rolling).

I can only make noise with built-in audio!

pd -listdev produces the following... start ->

Number of devices = 4
---------------------------------------------- #1
Name         = Built-in audio controller
Max Inputs   = 2, Max Outputs = 0
Sample Rates = 44100.00,
Native Sample Formats = paFloat32, 
---------------------------------------------- #2
DefaultInput
Name         = Emagic EMI 2|6
Max Inputs   = 2, Max Outputs = 0
Sample Rates = 44100.00, 48000.00, 96000.00,
Native Sample Formats = paFloat32, 
---------------------------------------------- #3
Name         = Built-in audio controller
Max Inputs   = 0, Max Outputs = 2
Sample Rates = 44100.00,
Native Sample Formats = paFloat32, 
---------------------------------------------- #4
DefaultOutput
Name         = Emagic EMI 2|6
Max Inputs   = 0, Max Outputs = 2
Sample Rates = 44100.00, 48000.00, 96000.00,
Native Sample Formats = paFloat32,

While pd -audioindev 2 -audiooutdev 4 produces...

And no sound from my Emagic emi 2|6 audio interface
(which works well with all other apps).  

Any thoughts?


thanks,
