I am creating voice recording application...Its working fine when I start the application. after some time I face 2 problems..
1. It stops recording. I can listen my sound from mic to earphone.
2. In ipod When I plug out mic and plug it in again..I am unable to listen recorded sound...
I think there is some problem in routing....
please help me out..
I am using following Code...

if ( audioSession.inputIsAvailable) {
[audioSession setCategory:AVAudioSessionCategoryPlayAndRecord error:&err];

NSLog(@"connected");
}
else {
NSLog(@"Not connected");

UInt32 category = kAudioSessionCategory_MediaPlayback;
AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(category), &category);

}

You should not be setting the audio session property directly if you are using CocosDenshion, you should set the mode on CDAudioManager. However, that is unlikely to be the cause of your problem.

You need to test your code on an iPhone as the behaviour is different to an iPod with a microphone plugged in. When you start recording on an iPhone the audio will switch from the main speaker to the in call speaker which has lower volume, you need to redirect the audio route. This is why I thought you would have audio routing code. The code is in Apple's Audio Session programming guide.

If it is working on the iPhone then you must have code to change the default audio route. That isn't the code you posted.

Every thing you need to know is in Apple's Audio Session Programming Guide. That is how I learnt.
