Uh, yeah.  We consider using AppleScript from an otherwise Objective-C 
app for anything other than user-supplied scripts to be bad form, 
because it's wildly inefficient.  In particular, you shouldn't use it 
just because you can't find the real API.  Appropriate tool for the 
job, and all that.  AudioDeviceGetProperty and AudioDeviceSetProperty 
are the calls you want.
