  An alternative is to port it to use a different API, like portaudio.   
http://www.portaudio.com

  I used PortAudio for EchoMac, because it was pretty straightforward to 
move the soundcard.h stuff over, and also it had the advantage of then 
calling CoreAudio stuff directly on the Mac, OSS on Linux, etc...  It 
wasn't going through yet another program like the esd daemon to get you 
to the hardware.

  I've had my fun porting from Linux to the Mac, it's time for someone 
else to have fun. All the source code I used in EchoMac is available, 
and the bundle includes the EchoMac GUI, the portaudio stuff, and the 
echoLinux code modified to use portAudio. It should be enough to get 
someone started in some direction or other... ;-)
