Was having issues with game audio shutting down the music app (or my case Spotify).

It looked like something may have changed with how the categories are handled? So I moved the audio session init to before alcOpenDevice. I modified my local Monkey modules/mojo/native/mojo.ios.cpp and game & external music now play/mix nicely together.

kAudioSessionCategory_UserInterfaceSoundEffects is also now deprecated.

gxtkAudio::gxtkAudio():musicState(0),musicPlayer(0),musicVolume(1){

	// BMH - set the session category to ambient (works with other music apps)
	AudioSessionInitialize( NULL,NULL,NULL,NULL );
	UInt32 sessionCategory = kAudioSessionCategory_AmbientSound;
	AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);
	UInt32 allowMixWithOthers = true;
	AudioSessionSetProperty(kAudioSessionProperty_OverrideCategoryMixWithOthers, sizeof(allowMixWithOthers), &allowMixWithOthers);
	AudioSessionSetActive(true);

	if( (alcDevice=alcOpenDevice( 0 )) ){

		//Magic Siread code allows audio to mix with user music...
		/* BMH - disabled as this is handled before alcOpenDevice
		AudioSessionInitialize( NULL,NULL,NULL,NULL );
		UInt32 sessionCategory=kAudioSessionCategory_UserInterfaceSoundEffects;
		AudioSessionSetProperty( kAudioSessionProperty_AudioCategory,sizeof(sessionCategory),&sessionCategory );
		
		UInt32 allowMixing=true;
		AudioSessionSetProperty( kAudioSessionProperty_OverrideCategoryMixWithOthers,sizeof(allowMixing),&allowMixing );
