Summary:
I'm trying to play an ADTS AAC file with AVAudioPlayer on iOS6, after setting the currentTime to an initial value.
This worked perfectly in my app when running on iOS <= 5, but in the latest iOS6 beta, the file would stop playing after a few seconds and the delegate will be informed the file was played successfully.

Steps to Reproduce:
Try to play an AAC ADTS audio file with AVAudioPlayer, after setting currentTime to any value (I used 2).

Example code:
    self.player = [[AVAudioPlayer alloc] initWithData:[NSData dataWithContentsOfMappedFile:[[NSBundle bundleForClass:[self class]] pathForResource:@"file.aac" ofType:nil]] error:&error];
    self.player.delegate = self;
    [self.player prepareToPlay];
    self.player.currentTime = 2;
    [self.player play];

Expected Results:
The file would play from the point set until the end of the music without stopping.

Actual Results:
The sound stops playing after a few seconds, the player calls the delegate method:
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
with a successful flag

Regression:
In iOS <= 5 this code works (the file is played until the end)
