   Hi!

   What's the easiest way to add sound to my game e.g. background music and sounds on actions?

   Thanks
   -Alex

   That would be library CocosDenshion and the SimpleAudioEngine interface.

   OK I've added the CocosDenshion folder conrtaining SimpleAudioEngine.* to my project and I've added the following frameworks:
   AudioToolbox, AVFoundation and OpenAL...

   but how do I set up the class files to play a background sound????

   Did you even read the link I posted? Here is the code to play a sound file called "mysound.wav" that is in the root of your project.

   [[SimpleAudioEngine sharedEngine] playEffect:@"mysound.wav"];

   yes, I've added that code :-) in my GameScene.m
   -should it be somewhere else?
   -is ogg format OK?

   I get one build error:
   *Building target "Game" of project "Game " with configuration "Debug" - (1 error)
   *Linking /Users/alex/......
   *".obj_clas_name_SimpleAudioEngine",referenced from:
   literal-pointer@_OBJC@_cls_refs@SimpleAudioEngine in GameScene.o
   symbol(s) not found
   collect2: Id returned 1 exit status
   *Build failed (1 error)

   Where is my mistake?

   OK all works well when starting with the MyFirstGame template in the 0.8 version... otherwise its a matter of fixing linking and dependencies with is causes more errors than I thought.
   A good guide on this would help newbies like me :-)

   "A good guide on this would help newbies like me :-) "

   agreed. However - cocos comes with plenty of code examples that explain how things work - and some of us feel thats the best way to learn anyway. If after going through the code and learning how it works you feel like writing a guide to cocos that would be very appreciated.

    Yes, please write one. I've already spent lots of time trying to make SimpleAudioEngine easy to understand but obviously I haven't made it simple enough.

    "... otherwise its a matter of fixing linking and dependencies with is causes more errors than I thought."

    I checked this out and it is wrong. You just need to add the files in the CocosDenshion folder to your project and make sure the 3 frameworks that are detailed in the FAQ have also been added. From memory someone had a similar linking error to yours because they had included multiple copies of the CocosDenshion files in their project.
