iOS Audio suddenly stops with an error

I received a error about my audio rate and asked 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?

Found the answer here. In case anyone else finds this post I had to adjust my sound input in the system preferences to line in. I purchased a new USB mic a few days ago and changed these settings which screws up the simulator.

The solution that lead me down the right path is here
