i have an app always working till i have installed ios5 on device.
this is the code.

Code:

UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;

        AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);    

        UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;

        AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride);

        //NSLog(@"url");

        NSURL *url = [NSURL fileURLWithPath:@"/dev/null"];

        //NSLog(@"dizionario");

        NSDictionary *audioSettings = [NSDictionary dictionaryWithObjectsAndKeys:

                                       [NSNumber numberWithFloat: 44100.0],                 AVSampleRateKey,

                                       [NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey,

                                       [NSNumber numberWithInt: 1],                         AVNumberOfChannelsKey,

                                       [NSNumber numberWithInt: AVAudioQualityMax],         AVEncoderAudioQualityKey,

                                       nil];

        NSError *error;    

        bool b;

        //NSLog(@"audio");

        recorder = [[AVAudioRecorder alloc] initWithURL:url settings:audioSettings error:&error];

        //NSLog(@"audio");

        if (recorder) {

            //NSLog(@"prepara");

            b=[recorder prepareToRecord];

            //NSLog(@"%@",(b ? @"OK" : @"NO"));

            //NSLog(@"meter");

            recorder.meteringEnabled = YES;

            //NSLog(@"recorder");

            b=[recorder record];

            //NSLog(@"%@", (b ? @"OK" : @"NO"));            

            //        NSLog(@"leveltimer");

            //        levelTimer = [NSTimer scheduledTimerWithTimeInterval: 0.03 target: self selector: @selector(levelTimerCallback:) userInfo: nil repeats: YES];

        } else {

            NSLog(@"************** ERRORE: ****************");

            NSLog([error description]);    

        }

the result is that recorder record silence, no peak power, no avarage power.
i use xcode4 (ios inxcode4 is till 4.3, i have not downloaded the latest xcode)
why in ios5 doesn't work anymore?
is not compatible?
thanks

I'm not sure it should ever have worked with the session set to kAudioSessionCategory_MediaPlayback.

solved but don't know why it stopped working.
the code above was putted in a singleton class loaded and initialized once at start of the app.
seems that records only one voice power then stops (even if i have controlled that recording=true, metering enabled=true ecc...in logs)
now i have putted the same code in a method of the singleton class and called that method from the file of the screen "ingame" and works...
mmm.......any ideas why it happens?
