I think I know what the problem is -- my app is being suspended. Even though I have the "audio" key added to the plist file, there is this sentence (best imagined as narrated by an ominous, deep voice with a thick reverb) from the iPhone Application Programming Guide: "However, if this key is not present when the application moves to the background, or if your application stops playing audio while in the background, your application is suspended." I think what is happening is that if iOS4 catches my app not playing audio in the background (like if it calls AudioQueueStop() even if it's going to call AudioQueueStart() later), it suspends it.
