[Stk] RtAudio and Stk interface

[Gary Scavone]

Hi Alpana,

I have 10.5.5 and an Intel Mac and I haven't had problems with Stk  
4.3.1.  What version of g++ are you using?  Download the current  
version, run "configure" in the root directory of the distribution,  
then go to the "projects/examples" directory and type "make  
audioprobe".  Then run the compiled application to see what devices  
and capabilities RtAudio is finding.

Regards,

--gary
