You are calling AudioHardwareSetProperty incorrectly. The obvious problem is that you are passing NULL for the inPropertyData when you should be passing the address of a CFRunLoopRef that is set to NULL. The other problem is that AudioHardwareSetProperty is deprecated and you should use AudioObjectSetPropertyData. The code would look like this:

  CFRunLoopRef theRunLoop = NULL;
  AudioObjectPropertyAddress theAddress =
{ kAudioHardwarePropertyRunLoop, kAudioObjectPropertyScopeGlobal,
kAudioObjectPropertyElementMaster };
  OSStatus theError = AudioObjectSetPropertyData
(kAudioObjectSystemObject, &theAddress, 0, NULL, sizeof(CFRunLoopRef),
&theRunLoop);

This should probably be the first call into the HAL that the process
makes. So sticking it somewhere near the beginning of main() is a good
idea.


Thanks that fixed the problem!

Any other possible breaking change that SL introduces? Is there any CoreAudio change list somewhere?

Thanks
