AudioPlayer not playing on a second view controller - objective-c

Question

I have a sound playing on buttons pushed from the main view controller which works fine. On the next view controller I also want a sound to play on buttons pushed but I'm not getting any sound. I set the two .h and .m files the same. What could my problem be? Thank you for any help.
my .m file:
#import "AboutView.h"
#import <AVFoundation/AVFoundation.h>
#import <CoreAudio/CoreAudioTypes.h>
#interface AboutView ()
#end
#implementation AboutView
#synthesize support;
#synthesize facebook;
#synthesize kmbdev;
#synthesize back;
#synthesize player2;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNi{
if (self) {
// Custom initialization
}
return self;
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource: #"sound1" ofType: #"wav"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: soundFilePath];
self.player2 = [[AVAudioPlayer alloc] initWithContentsOfURL: fileURL error: NULL];
player2.volume = .5;
[player2 prepareToPlay];
}
My .h file:
#import "ViewController.h"
#import <MessageUI/MessageUI.h>
#import <AVFoundation/AVFoundation.h>
#import <CoreAudio/CoreAudioTypes.h>
#class ViewController;
#interface AboutView : UIViewController <MFMailComposeViewControllerDelegate, AVAudioPlayerDelegate>{
AVAudioPlayer *player2;
}
#property (strong, nonatomic) IBOutlet UIButton *back;
- (IBAction)back:(id)sender;
#property (strong, nonatomic) IBOutlet UIButton *support;
#property (strong, nonatomic) IBOutlet UIButton *facebook;
#property (strong, nonatomic) IBOutlet UIButton *kmbdev;
- (IBAction)email:(id)sender;
#property (strong, nonatomic) AVAudioPlayer *player2;
#end
I have [player2 play]; at my prepare for segue and IBaction as I do on the main view controller.

Add this code in ViewDidLoad method of 2nd controller:
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource: #"sound1" ofType: #"wav"];
if([[NSFileManager defaultManager] fileExistsAtPath:soundFilePath)
{
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:soundFilePath];
if(fileURL)
{
self.player2 = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil];
self.player2.delegate = self;
self.player2.volume = 0.5f;
[self.player2. play];
}
}
else {
NSLog(#"File DoesNot Exists");
}
