RE: [PD] Audio trouble (2 in 6 out refused) - Mac OS X

From what I've heard on this list, portaudio (PD's sound engine) does not allow more ouputs than there are

inputs. This is from an email from one of the portaudio developers. There may be some workarounds available, depending on the card's chipset and what open source drivers are available for it (try kxproject and emu101 or something like that). I was about to buy an Audigy 2 NX, but I'm holding off until I know whether there is a workaround possible. Please let me know if you figure it out.

Hi all,

Two sound card issues that you may resolve (I use the stable package from Hans for Mac OS X):

1 - I've got an annoying problem with my audio settings: I have an USB

5.1 box, wich work natively with core audio, but if I try to set as 2 input / 6 output it gave me the following error:

 error: portaudio: number of input and output channels must match

if I try to "lie" to PD, setting 6 in / 6 out, I logically got:

  Error number -9999 occured opening portaudio stream
  Error message: Invalid number of channels.

Is it a known PD issue? Or is it an OS X issue?

2 - Is there a way to use multiple sound interface simultaneously with

PD. I have a project where I would like to gather the input (very basically : sound/no sound) from dozens of sound inputs.

Thanks to all for the riche information I have found here, and special

thanks to all the developpers and packagers!
