[Portaudio] Channel name in Mac OSX

[Bjorn Roche]

Hello Gil,

	I'm afraid there is no PortAudio interface to retrieve this  
information, nor is there an interface for selecting specific  
channels, although there have been discussions of the latter. If you  
wanted to submit a patch to add this functionality, I would gladly  
look it over and apply it if it looks good.
