In my case, the setup code goes all the way through to the call to startReading and the first call to copyNextSampleBuffer (which is used to prime the AudioQueue). All that is done within the same thread.

I've not tried creating and configuring the AVAssetReader on the audio thread (probably because it seems like a bad idea, although I'm certainly willing to try bad ideas to solve this issue!).

What I _have_ tried (in a similar vein) is calling -[AVAssetReader startReading] on the audio thread. That alone did not solve this issue.
