If a timer goes off or you receive an incoming call, monkey audio stops, and will not play again, until the Monkey app is restarted.

PlaySound() will not work, I think PlayMusic() might.

I'm on v75a, Xcode5 and can reproduce the error on iPhone 4, iOS7 and iPad 4th gen iOS 6
this way:

1) Run bananas/mac/suspendtest
2) Start the app , and make it loop a sample
3) Click HomeButton to set a timer to go off in the next 1 or 2 minuttes.
4) go back to suspendtest and notice it's playing audio.
5) when the timer pops up on top, click ok.
6) Sound is now not working in suspentest anymore.

[EDIT] : Just tested on iOS 6.1.3 , iPod thouch 4 gen, Xcode 5, Monkey 76a and the problem remains the same.

I think I have found a cure for this!

Taking a cue from http://benbritten.com/2009/02/02/restarting-openal-after-application-interruption-on-the-iphone/

in gxtkAudio::Suspend()

'... existing code, then add /before Return 0) :

    // Deactivate the current audio session
    AudioSessionSetActive(NO);
    //Next, shut down openAL in a nice way so you can keep your context intact:
    
    // set the current context to NULL will 'shutdown' openAL
    alcMakeContextCurrent(NULL);
    // now suspend your context to 'pause' your sound world
    alcSuspendContext(alcContext);

in gxtkAudio::Resume()

    
    // Reset audio session
    UInt32 sessionCategory=kAudioSessionCategory_UserInterfaceSoundEffects;
    AudioSessionSetProperty( kAudioSessionProperty_AudioCategory,sizeof(sessionCategory),&sessionCategory );
    
    UInt32 allowMixing=true;
    AudioSessionSetProperty( kAudioSessionProperty_OverrideCategoryMixWithOthers,sizeof(allowMixing),&allowMixing );
    
    // Reactivate the current audio session
    AudioSessionSetActive(YES);
	
    // Restore open al context
    alcMakeContextCurrent(alcContext);
    // 'unpause' my context
    alcProcessContext(alcContext);

  '... existing code here
