HI!!! all I am using OS X driver 1.3b0 (BETA) for my Audigy 2 ZS with OSXLION 7.2. I am using the following code to play a sound cocos2d and it just wont play Code: [[SimpleAudioEngine sharedEngine] playEffect:@"pew-pew-lei.caf"]; I read through other forums and found that I had to use 42000 Hz .... but it is not allowing me to change the settings in the Audio MIDI setup.... How do I change it? or is there anything else that I could do to make it play the sound. By the way ... all other sounds play just fine... regards..
