Apple

I want to call the synchronous AudioQueueStop(AQRef, true) method. The Problem with this is, that it crashes the entire App. It seems to be a Problem with the output callback function somehow (altough i have no code in the callback function). Removing existing property listeners also didn't help (as sugessted in another thread). I tried the stop method on the main thread and on dispatched ones... same result. Here's the stack trace...
