Answer 1

use AudioToolBox instead of AudioUnit even i was having same problem. it got solved by using audiotoolbox. For playing frequency check this code "/Developer/Examples/CoreAudio/SimpleSDK/DefaultOutputUnit" and http://atastypixel.com/blog/2008/11/04/using-remoteio-audio-unit/

m also doing the same thing. hope so it will help you.
