I am making the scary leap of diving into CoreAudio. I have downloaded the apple Demo titled "LoadPresetDemo". I have made no modifications to the original code from apple. When I try to run it, it compiles without error, but the simulator freezes and it it says "Thread 1:singal SIGABRT". There are then 9 threads listed in the debug window. I have included the command line info below if that helps anyone figure out what is going on, but I should be able to run something written by apple without a problem. I have Digidesign Protools installed on this computer if that info is of any use. I am in over my head here and I have no Idea what to do next. Can anyone help me?
