iphone - play audio stream in background - iphone

Question

I'm using xcode 4.2 and building an iphone app, and have a view that when opened plays an audio stream.
What i try to achieve is have the app continue playing even if it enters the background.
I've tried any possible solution that i found in stackoverflow or elsewhere (and there are many available), but can't get it work. When the application enters background the audio stops, when i open the app again the audio continues.
In my Info.plist ia have set 2 rows:
Required Background Modes -> App plays audio &
Application does not run in background -> NO
What am i missing? what else is needed to keep playing the audio in the background?
Thank you in advance.
EDIT:
I see many answers on the issue, suggestiong the use of AVAudio Framework. Is there any chance that MPMoviePlayerController is not able to play the stream in the background? Should i change to AVAudio?
EDIT 2:
Ok, seems it's too complex for me to achieve. I'm giving the exact code, hope this will help.

Answer 1

Check your audio session setup as that might need some extra attention.
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback
error:nil];
[[AVAudioSession sharedInstance] setActive:YES
error:nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

How stumbled upon the programming tutorial in details at this place.

This should play the music within the app and also continue to play if you take your app in background.
