CocosDenshion not playing effects?

I've just started messing with CocosDenshion, but I can't get the SimpleAudioEngine to play effects.

		[SimpleAudioEngine sharedEngine].muted = NO;
		[SimpleAudioEngine sharedEngine].effectsVolume = 1.0;
		ALuint soundId = [[SimpleAudioEngine sharedEngine] playEffect:@"Fanfare.wav"];
		NSLog(@"Played effect id %d", soundId);
		//[[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"Fanfare.wav"];

This is a fresh cocos2d 0.82 project, and I've pasted the above to the bottom of the HelloWorld init method.

Here is the debug output:

The problem is, no sound was output at all. If I uncomment the line that calls playBackgroundMusic, it plays it (and loops). I've tried short sound effects (less than 1 second) and a 15 second clip to no effect. Is there some special setup needed to play effects?

Please follow the general troubleshooting steps outlined in the FAQ:

None of those steps apply to me.
I'm using an Intel based macbook. Sound output is directed to the internal speakers, and input is directed to the internal microphone. There's no option to direct to the simulator.
It DOES output sound - but only if I use playBackgroundMusic. If I use playEffect, it doesn't produce sound.

I've also tried using playEffect WHILE background music is running (even the SAME wav file). The BG music runs and loops, but playEffect still doesn't play anyhing (though it SAYS it is).

It turns out it will work on the iPhone itself... the problem only occurs in the simulator.

I DON'T think YOU read that LINK properly. Those STEPS apply to EVERYBODY and are still APPLICABLE.

They are about logically determining whether the problem is with your project, your environment or CocosDenshion. The first step is to run the CocosDenshion demo to see if you also have playback problems with that.

It sounds like you have an issue with OpenAL, you can confirm that by running some other OpenAL based code like Apple's oalTouch example.

I read the ENTIRE link, and it still doesn't work. Since faqs tend to get stale, I figured I'd check here before posting a bug report.

oalTouch and avTouch work. CocosDenshion does not. And none of those issues mentioned in OpenAL problems apply to me because I'm using a stock intel macbook with output set to internal speakers/internal mic, and no DivX codec (or any codec) installed. This is a work machine with no additional software installed besides xcode, firefox, and open office.

If oalTouch works and the CocosDenshionDemo doesn't then I have no idea what is wrong.

You can also try the sound engine that ships with cocos2d under the experimental directory, it would be interesting to know whether that works or not - the demo is PASoundEngineTest.

Ok, I grafted PASoundEngineTest into a fresh project and gave it a whirl.

I had to comment out the ogg support since I couldn't get vorbis working (it was expecting a very old version of the vorbis library). I converted the trance loop to wav instead.

It works on the iphone but not in the simulator. Not even the background track works in this program =/

The images "b1.png" and such were not included, so I just copied over some small pngs as placeholders. What's really weird is that the bottom menu doesn't even show up in the simulator, but it does show up in the iphone...

I've got the same issue. It's been working this whole time until my last revision. I'm looking through my code changes for any reason it may have happened.

Hello, this is perhaps an obsolete answer but today I had to fiddle with the muted property of the SimpleAudioEngine, since your code in OP starts with this line:
[SimpleAudioEngine sharedEngine].muted = NO;

Have you tried to run this code without this line, I had some trouble with the SimpleAudioEngine while setting:
[SimpleAudioEngine sharedEngine].muted = NO;
my program wouldn't playback any sounds. On the other hand if i did this:
[SimpleAudioEngine sharedEngine].muted = YES;
[SimpleAudioEngine sharedEngine].muted = NO;

Then everything thing worked fine again.
The second value is supposed to come from my config file. Leaving out all muted code also works fine because standard the sound-engine inits as unmuted.

Right now, I have trouble reading in my config file that has muted flag set to true, the game is muted but going into settings and toggling my sound enabled disabled switch doenst work. If i leave sounds on, save settings, exit program and restart my app then sound comes back properly. To me it appears that if the sound engine is already muted or not muted, to not set the same value again???

I'm going to investigate some more.
Regards Jeroen

@fotoboer.nl - if you encounter problems it is a good idea to check what changes have been recently made to the source code here

http://code.google.com/p/cocos2d-iphone/source/list

If you look at r1834 you'll see it fixes the issue you are describing, however, it was a 0.99 specific issue.
