On iPad, why does AVAudioSessionCategoryAmbient stop the music playing in iPod?

The following code is supposed to play a sound and won't stop the music playing by iPad's Music/iPod. (on iOS 5.1, the iPod app became the Music app).

It is using AVAudioSessionCategoryAmbient instead of AVAudioSessionCategorySoloAmbient. But it actually stopped the music in either case. Is there something wrong with the use of AVAudioSessionCategoryAmbient?

NSURL *sound0URL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"0" ofType:@"aiff"]];

audioPlayer0 = [[AVAudioPlayer alloc] initWithContentsOfURL:sound0URL error:nil];

audioPlayer0.delegate = self;
[audioPlayer0 prepareToPlay];

NSError *setCategoryErr = nil;
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:&setCategoryErr];

NSLog(@"%@", setCategoryErr);

audioPlayer0.currentTime = 0;
[audioPlayer0 play];

the setCategoryErr is printed as (null) so there should be no error.

As I said in my comment, it seems the solution is to set the AVAudioSession category BEFORE calling prepareToPlay on the AVAudioPlayer.
