   I'm not sure if this is just me having this issue, or maybe I'm simply mistakingly doing something horribly wrong here. What I thought was a simple implementation ended up being something much more complex.

   So in my game I'm playing a background sound file, works like a charm.

   [[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"MoleMusic.aif" loop:FALSE];

   And then I thought, "Hey let me add in a sound effect when something happens" so I immediately put this:

   [[SimpleAudioEngine sharedEngine] playEffect:@"Sound.aif"];

   And it didn't work. it doesn't work with "aif", "caf", or "wav". It doesn't work with my background music which is just under 30 seconds so should qualify as a valid effect file. I tried making a blank project and it didn't work in there either. And just to clarify I am including the "SimpleAudioEngine.h" file to my project file as well.

   Anyone have any hints, recommendations, inside loop to a psych ward before I go crazy? :)

   I'm pretty sure you need to put the full path reference in the playEffect method in the latest version of SAE, not just the filename. Try something like this:
   [[SimpleAudioEngine sharedEngine] playEffect:[[NSBundle mainBundle] pathForResource:@"Sound" ofType:@"aif"]];

   That fixed it for me.

   Hey jamesphipps. I appreciate your reply, thanks!

   I did try using your method and unfortunately came through with the same results. I'm beginning to think maybe my export method could be off? I'm using Soundtrack Pro and using a native File > Export.. and as an AIF, CAF, and WAV without any luck. Anyone know what kind of encoding, bit rates, etc, that may be requirements?

   CocosDenshion also ships with demos. TomTheTurret is using SimpleAudioEngine. If you have problems then the first step should be to try one of the demos to see whether the issue is your project or your environment.

   Hey Steve,

   Sorry I forgot to mention I fixed this issue actually. I did additional troubleshooting and actually snatched the effect sound file from TomTheTurret demo and it worked in my environment. The way sounds get exported by default through Soundtrack Pro aren't compatible with the SimpleAudioEngine. So if anyone else runs into this issue and are using Soundtrack Pro, just do this:

   1) File > Export.. (.aiff)
   2) Open Quicktime
   3) File > Save As.. (.aiff with 22.050 khz, and 16 bit)
   4) Rename file extension to .caf
   5) Use file :)

   That's what worked for me at least. Thanks guys!
