iphone 3gs, 5.1.1, audio problem

Hi. I’m testing my game on iphone 3gs (ios 5.1.1) and having a problem with audio resuming. After manually suspending/resuming my game works fine and background music is resuming. But after receiving incoming call game cannot resume background music, btw all sounds are playing still fine. I can resume music only by pressing sound button in menu. Does anyone have the same problem? [import]uid: 118965 topic_id: 37623 reply_id: 67623[/import]
