I received a error about my audio rate and asked to restart the simulator. Code: <com.apple.audio.HALB_DispatchQueue.SerialQueue> Default audio device changed. Restart the simulator to have it use the newly-selected device. 2012-11-29 18:14:20.046 XP Tracker[2708:19807] <0xb02e3000> Audio device's sample rate changed. You may need to restart the simulator. I am just testing it on the simulator and I have not changed the audio file or messed with the code in that class. Has anyone else gotten a message like this before?
