AVAudioPlayer error loading file

Question

I am trying to use the AVAudioPlayer to play a simple sound and I keep getting this error in the console:

2011-09-02 20:29:07.369 MusicLog[967:10103] Error loading /System/Library/Extensions/AppleHDA.kext/Contents/PlugIns/AppleHDAHALPlugIn.bundle/Contents/MacOS/AppleHDAHALPlugIn:  dlopen(/System/Library/Extensions/AppleHDA.kext/Contents/PlugIns/AppleHDAHALPlugIn.bundle/Contents/MacOS/AppleHDAHALPlugIn, 262): Symbol not found: ___CFObjCIsCollectable   Referenced from: /System/Library/Frameworks/Security.framework/Versions/A/Security   Expected in: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation  in /System/Library/Frameworks/Security.framework/Versions/A/Security 

Here is my code that should play a sound when my button is pressed:

NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"tick" ofType:@"caf"]; NSError *error;      NSURL *soundURL = [NSURL fileURLWithPath:soundPath];     AVAudioPlayer *tickPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundURL error:&error]; [tickPlayer setDelegate:self]; [tickPlayer setNumberOfLoops:0]; [tickPlayer prepareToPlay]; if (tickPlayer == nil) {     NSLog(@"%@", [error description]); } else {     [tickPlayer play]; } 

Do I somehow have the file in the wrong place? I just dragged the file into the project and selected copy if needed.

EDIT: After more testing I found that I do not get this error when running IOS 4.2 simulator, only on the IOS 5 simulator. Can I assume that this is a bug in iOS 5?

Thanks,

I've had the same problem. It only seems to be a problem on iOS5 in simulator. I haven't tested on an iOS 5 device yet. I keep hoping XCode upgrades will make the error go away, but so far no luck.

I've had the same error, but the sound played nonetheless after I keep the variable as a class attribute. If the code that you put here is written inside a method, try moving this variable. I guess the sound didn't play because the audioPlayer instance is lost after the method went out of scope.

@implementation SomeAudioController {     AVAudioPlayer *tickPlayer; }
