[Ham-Mac] iMic sound ?

[Chuck Sherman [Moose@NIH.gov]]

does anyone know if the Mac, OS 9 or OS X, can be set up to issue 
sound through BOTH the internal speakers and the Griffin USB iMic?

I'm using the US Robotics SoundLink system transverter to provide 
iTunes audio through the house on 88.1 FM (after 900 MHz transfer to 
a remote receiver) and I don't want to have to shut off the internal 
speakers.
