Title: AudioUnitSetRenderNotification() returns badComponentSelector
Whenever I attempt to use AudioUnitSetRenderNotification(), the result code returned is badComponentSelector (-2147450878, “Component does not support the specified request code.”), and my callback is never called.
The AUs I have tried this with have been Apple’s Delay, the dev sample code’s SampleEffect, and Smartelectronix’s Ambience.
I am creating an AUGraph of several nodes (opening, initializing, and starting), getting the effect AudioUnit for the node I am interested in render notifications for, and attempting to pass this AudioUnit to AudioUnitSetRenderNotification(). The graph itself is functionaing and rendering audio as expected.
Does an AU need to be specially written to support this function? I was hoping to just tap into any I was interested in.
I'm not finding much of anything for documentation...
Many thanks.
Scott Puhl
