It seems Everyplay does not yet support AL_SEC_OFFSET which your audio code is using. To make the EveryplayFeatures work change it like this:
EveryplayFeatures.h
#import <Foundation/Foundation.h>
@interface EveryplayFeatures : NSObject
@end
EveryplayFeatures.m
@implementation EveryplayFeatures (Private)
+ (BOOL) supportsOpenAL {
return NO;
}
+ (BOOL) supportsCocosDenshion {
return YES;
}
@end
