   Hi all,

   I'm currently experiencing problems playing sounds using CocosDenshion (SimpleAudioEngine).

   This problem occurs in the Simulator but I've not yet tested it on an iPhone device.

   The 2 lines of code below are a 'hack' that fixes this problem...

   [[SimpleAudioEngine sharedEngine] resumeBackgroundMusic]; // hack
   [[SimpleAudioEngine sharedEngine] pauseBackgroundMusic]; // hack

   if([GlobalDataManager sharedDataManager].sfxOn == YES) {
   [[SimpleAudioEngine sharedEngine] playEffect:@"gameSound.mp3"];
   }

   Without the 'hack' the sound effect will not play, not too sure why though?

   If you have previously stopped the background music it will cause problems in the simulator.

   I also noticed you are using an mp3 format sound for playEffect. This could be part of the problem too. Do you realize that by using mp3 format sounds for playEffect that your effects will only play on OS 3.0 onward? It is recommended to use wave or IMA4 format sounds for playEffect (refer to the Wiki for more details).

   Hi Steve,

   I was aware of this issue and do not stop the music at any point, I resume it instead.

   Yesterday I tested this issue on an OS 3.0 iPhone and the sound played fine, not too sure why it would not play on the Simulator?

   I do plan to convert my audio files to IMA4 format in the future since I need my sounds to play on OS 2.2 upwards.

   I'd like to take this opportunity to thank you Steve for all your hard work on CocosDenshion, it really is the best sound engine out there and I highly recommend it to all iPhone developers.

   Okay, thanks for the info (and thanks). I'm not really sure what the issue is but the audio playback in the simulator is fairly dodgy. As long as it works on devices I won't lose any sleep.
