Even initializing openears causes this issue without saying anything.

This is the call:

[[SimpleAudioEngine sharedEngine] playEffect:POPING_SOUND pitch:1.0f pan:0.0 gain:1.0];

As long as I initialize:

self.fliteController = [[FliteController alloc] init];

No sound comes out. I should mention the POPING_SOUND is a wav file.

Thanks for the help, I really like the engine but it needs to work with sound.

The underlying issue is that OpenEars’ sound requirements add up to an additional audio engine’s worth of code, so there is probably an unwanted interaction between OpenEars’ audio session handling and SimpleAudioEngine. A search through this forum for “audiosession” and/or “allowmixing” should turn up some explanations of how to turn on mixing for different audio streams/sessions, which would be the first troubleshooting step. This issue:

/forums/topic/openears-avplayer-issue/

Probably has very similar underpinnings, so it is probable worth a read to debug the issue you’re seeing.

I got the same problem.

Did you find a workaround?

Thanks.

OpenEars isn’t expected to work alongside another audio engine, since they will be addressing the same resources.

I added this line of code:

    NSError *error;
    [[AVAudioSession sharedInstance]
     setCategory:AVAudioSessionCategorySoloAmbient error:&error];

- (void) stop {
    if (self.openEarsEventsObserver) {
        self.openEarsEventsObserver.delegate = nil;
        self.openEarsEventsObserver = nil;
    }
    if (self.pocketsphinxController)  {
        [self.pocketsphinxController stopListening];
        self.pocketsphinxController = nil;
    }
    
    NSError *error;
    [[AVAudioSession sharedInstance]
     setCategory:AVAudioSessionCategorySoloAmbient error:&error];
}
