This is a bit of a long shot but are you sure that you're not looking
at a multi-threading issue? I would move the call to AudioQueuePause
and AudioQueueStart to the main thread (look at
-performSelectorOnMainThread) to see what this does, the interrupt is
probably coming in on a different thread than your player is on.
