SimpleAudioEngine not playing sounds?

Hi all,

I just started using SimpleAudioEngine and am noticing that some sounds play and some do not. I've tried calling preloadEffect: on all WAV files but it doesn't seem to help. The problem also appears to be inconsistent... some sounds play some of the time and others never play at all.

Basically, I'm calling SimpleAudioEngine as follows:

[[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"intro1.mp3" loop:YES];
// wait for tap
[[SimpleAudioEngine sharedEngine] stopBackgroundMusic];
[[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"intro2.mp3" loop:YES];
// wait for tap
[[SimpleAudioEngine sharedEngine] stopBackgroundMusic];
[[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"background.mp3" loop:YES];
[[SimpleAudioEngine sharedEngine] playEffect:@"effect1.wav"];
[[SimpleAudioEngine sharedEngine] playEffect:@"effect2.wav"];

For example, effect1 may or not play and effect2 will never play, etc.

I'm using SVN revision 1329 although it was occurring with 8.0.1 as well.

Any thoughts?

Are you 100% sure that you are using 1329 because this is exactly the same as a bug fixed by CJ recently? How did you get 1329 and did you clean your build after getting it?

Also what format is the sound that never plays? Refer to the Wiki for details of using afconvert to convert wave files to the correct format for playback with CocosDenshion.

Also this isn't in the simulator is it? If so, there is a bug with stopBackgroundMusic in the simulator that screws up the sound effect playback. Use pauseBackgroundMusic instead when you are running in the simulator.

Hi Steve,

Thanks for chiming in. I did a manual checkout from SVN and it told me that it was revision 1329. I copied the files in the CocosDenshion folder over to my project, did a clean and build.

I tried running afconvert on my wave files (as shown on the Wiki) and that caused one of the effects to play that wouldn't before. However, I'm still seeing certain effects play sporadically. It almost seems like in one build they work and a subsequent one they don't. This is both in the simulator and on the iPhone 3.0 device itself.

I'm afraid I can't offer much advice based on such vague symptoms. If you can create a minimal example that recreates the problem I will look at it but obviously what you are doing isn't complicated and it is working for other people.

And remember on the simulator do not use stopBackgroundMusic.

Okay, I'll see what I can put together.

@Steve Oldmeadow thanks, I was figure out why all sounds suddently stop playing. So if we use stopBackgroundMusic on simulator, all effectMusic also stop. Must put this in wiki so others member know it.

^ It has been in the Wiki for a long time:
