Ios 等待5200毫秒以更新属性的属性数据时超时

我设置在我的应用程序中录制音频，如下所示：

AVAudioSession *audioSession = [AVAudioSession sharedInstance];
NSError *err = nil;
[audioSession setCategory :AVAudioSessionCategoryPlayAndRecord error:&err];
if(err){
    NSLog(@"audioSession: %@ %d %@", [err domain], [err code], [[err userInfo] description]);
        return;
}
err = nil;
[audioSession setActive:YES error:&err];
if(err){
    NSLog(@"audioSession: %@ %d %@", [err domain], [err code], [[err userInfo] description]);
    return;
}
self.recordSetting = [NSMutableDictionary dictionary];
[_recordSetting setValue :[NSNumber numberWithInt:kAudioFormatMPEG4AAC] forKey:AVFormatIDKey];
[_recordSetting setValue :[NSNumber numberWithFloat:kMusicSampleRate] forKey:AVSampleRateKey];
[_recordSetting setValue :[NSNumber numberWithInt: 1] forKey:AVNumberOfChannelsKey];
[_recordSetting setValue :[NSNumber numberWithInt:AVAudioQualityHigh] forKey:AVEncoderAudioQualityKey];

在iPhone4、4s和5中，一切都正常运行。但有些5s有这样的错误：

ERROR:    13:57:30.310 [tid 0x102dd8000] [298]: timed out waiting 5200 milliseconds for property data to be updated for property [goin/glob/0] (property was updated = 0, error = 0)
