No audio interrupt notification when using AVPlayer

Product:iPhone SDK Product Version:6.0
Classification:Serious Bug Reproducible:Always
 
Summary:
If I setup an audio session, then create an AVPlayer I do not get an audio interruption begin callback. If I don't create the AVPlayer everything works as expected. It seems like AVPlayer is manipulating my audio session or stealing away my callback, is there a way to prevent this?

I have tried releasing the AVPlayer or reasserting my audio session but nothing seems to help.

Steps to Reproduce:
Run the provided app, you will hear the AVPlayer play, cause an interruption (double tap home, swipe right, play some music), notice no TTY output even though I have an interrupt callback registered. Now comment out the AVPlayer init and repeat the above, notice you do get TTY output.

Expected Results:
Application should receive interruption notification.

Actual Results:
No interrupt notification if AVPlayer is used.

Regression:
Works as expected on iOS 5.
