It would have been easier to diagnose the error without having to guess at the line number on which it occurs, but I think the issue is your use of the error instance variable to pass as the error here:

30    [audioSession setCategory:AVAudioSessionCategoryPlayAndRecord error: &error];

also here

49    [fm removeItemAtPath:[recordedTmpFile path] error:&error];

The reason is that, if an error occcurs, in setCategory:error: the existing value of error will be overwritten without being released and is thus a potential leak.
