   Hello, guys!
   I'm using SimpleAudioEngine in my game, and it doesn't play sounds correctly.

   I have a sound called torch.wav which I preload at the beginning of game,
   and it plays when scenes are changed.
   But problem is when I asked it to play game over.mp3/xxx.mp3/yyy.mp3, it also plays torch, not them. I checked all the sounds with itunes and it sounds exactly as they are(simple drum loop), but when I build and run the game, they all sounds torch. Some other sounds are played correctly.

   is there anyone who had this problem and solved it?
   Help!

   Oh, something is different from what I explained. At the first play of different sound, and also sometimes, torch.mp3 is played instead of the sound supposed to be played. Why is it?

   After I preloaded all the sounds, it didn't do such things, well, almost. For some reason it plays another sound right after playing a sound, which I didn't ask : (..

   Do you have the latest version of SimpleAudioEngine? This sounds exactly like a bug that was fixed by CJ last month. If you don't know how to get the latest version then read this thread:

   http://www.cocos2d-iphone.org/forum/topic/1367

   Also, I noticed you have "game over.mp3" if you are using playEffect to play this sound then you need to be aware your sound will only work on OS 3.0 onward. On older versions of the OS it will fail to load. You should use wave files or IMA4 for effects if you want your audio to work on older OS versions. Refer to the Wiki if you need more detail.

   Try unloading a sound after it's done playing.

   in your dealloc method

   [[SimpleAudioEngine sharedEngine] unloadEffect:@"yoursound.extension"];

   @artem - you only need to unload sounds if memory is an issue. If you need to unload sounds to get SimpleAudioEngine to work properly then there is a bug.

   Oops! Sorry

   I just thought that could solve the problem.

   Thanks!

   ^ no problems, I was just concerned that you had to do that to fix the problem you had last week. Is it working okay for you without having to unload sounds?

   @Steve Thanks for the solution! I feel to try that soon. It's quite sad that I can't use mp3 files for other versions, but really really good-to-know information. Thanks again. I think i just need to update the file and change file types into wavs.

   @artem That's okay, thanks for your tral! you are Sweet!
