Comment(by martinlagardette@…):

 The problem comes from multiple things actually:

  - The CoreAudio BridgeSupport file is incorrect. The
 `AudioDeviceCreateIOProcID` function is said to receive `^?` (pointer to
 something unknow), when it shall say a pointer to a function, because
 `AudioDeviceIOProcID` is actually typedef-ed to a function pointer.
  - MacRuby's BridgeSupport parser doesn't support pointers to function
 pointers. I have a local patch that fixes that, and might commit later,
 but:
  - MacRuby doesn't know yet how to convert a C function pointer to a Ruby
 Proc. I'll try to see if I can do that.

 In any case, even if I fix the two MacRuby's problems, CoreAudio's
 BridgeSupport is not correct and will have to be modified manually for it
 to work.
