ExtAudioFileOpenURL giving me problems

[glLoadIdentity]

I'm trying to get OpenAL working on the IPhone and the wav file I have isn't loading.

Here's my Objective C++ code

bool LSound::load_sound( const char* path )
{
	OSStatus err = noErr;

	//Open a file
	CFURLRef theURL = CFURLCreateFromFileSystemRepresentation(kCFAllocatorDefault, (UInt8*)path, strlen(path), false);
	if (theURL == NULL)
	{
		NSLog(@"File not Found!");
		return false;
	}
	
	ExtAudioFileRef extRef = NULL;
	
	err = ExtAudioFileOpenURL( theURL, &extRef );
	if(err)
	{
		NSLog( @"Unable to load file! Error Code:%ld", err );
		return false;
	}

The error code ends up being reported as -43.

Also, am I barking up the wrong tree? I need a sound API for the iPhone that doesn't lag and can play sound effects and music. Is there a better route than OpenAL?
