[PD] audio problem on OSX with a particular mixer

[Derek Holzer]

Hi Rene,

I think you can safely factor the mixer out of the equation, unless you 
believe in voodoo ;-)

Pd doesn't play well with Coreaudio or Portaudio at all, so using JACK 
is the best workaround for that. Lots of archive discussion on this 
topic, but no solutions...

Best,
Derek
