Cocos2d-iPhone 0.8 sound-engine woes

Question

Hey all, looking for some advice on using the experimental sound-engine in cocos2d-iphone v0.8. What I have done is to create a class called audioManager and house it in the appDelegate so that it is available to the whole application pretty easily. I don't instantiate the class until the splash page has started so it should atleast have a loading message to the user.

My problem is that the application takes about 10 seconds to start on the device (debugging and normal usage) and I'm only using the trance-loop.ogg they provide with the sample. This seems really slow and I'm looking for any advice on how I can improve this or if I should change over to the AVFramework or OpenAL.

Heres the code:

AppDel.h

#import <UIKit/UIKit.h>
#import "audioManager.h"

@interface HaloJumpAppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
    audioManager *sndManager;
}

@property (nonatomic, retain) audioManager *sndManager;

-(void)setAudioManager:(audioManager *)object;

@end

AppDel.m

#import "HaloJumpAppDelegate.h"
#import "cocos2d.h"
#import "SplashScene.h"
#import "Scene.h"

@implementation HaloJumpAppDelegate
@synthesize sndManager;

- (void)applicationDidFinishLaunching:(UIApplication *)application
{
    window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    [window setUserInteractionEnabled:YES];
    [window setMultipleTouchEnabled:YES];

    // set up Director, probably something like this:
    [[Director sharedDirector] attachInWindow:window];

    [window makeKeyAndVisible]; 

    // make a scene, probably something like this:
    SplashScene *scene = [SplashScene node];
    [[Director sharedDirector] runWithScene:scene];
}

// store the passed audioManager for use through app
-(void)setAudioManager:(audioManager *)object
{
    sndManager = object;
}

// get outta here
- (void)dealloc
{
    [window release];
    [super dealloc];
}

@end

audioManager.h

#import <Foundation/Foundation.h>
#import "cocos2d.h"
#import "PASoundMgr.h"

@interface audioManager : NSObject {
    BOOL playAudio;

    // sound list
    PASoundSource *mainMenuBackTrack;
}

@property (retain, nonatomic) PASoundSource *mainMenuBackTrack;
@property BOOL playAudio;

-(void)playMenuBackTrack;
-(void)setAudioEnabled:(BOOL)value;

@end

audioManager.m

#import "audioManager.h"
#import "PASoundSource.h"

@implementation audioManager
@synthesize playAudio, mainMenuBackTrack;
-(id)init {
    self = [super init];
    if (self != nil) {
     // ok lets initialise the sound manager
     [PASoundMgr sharedSoundManager];

     // add the background track
     mainMenuBackTrack = [[PASoundMgr sharedSoundManager] addSound:@"tranceloop" withExtension:@"ogg" position:CGPointZero looped:YES];  
    }

    // return instance
    return self;
}

// this option sets the audio mode to Enabled (1)
-(void)setAudioEnabled:(BOOL)value
{
    NSLog(@"audio toggled to :%d", value);
    playAudio = value;
}

// plays the main menu background track once
-(void)playMenuBackTrack {
    [mainMenuBackTrack setGain:0.8f];
    [mainMenuBackTrack playAtListenerPosition];
}

@end

splash.m

#import "SplashScene.h"
#import "AudioChoiceScene.h"
#import "cocos2d.h"
#import "audioManager.h"
#import "HaloJumpAppDelegate.h"

// the main splash scene
@implementation SplashScene
-(id)init
{
    // instantiate this class
    self = [super init];
    if (self != nil)
    {
     // add the main splash graphic
     Sprite *bg = [Sprite spriteWithFile:@"splash.png"];
     [bg setPosition:ccp(160, 240)];
     [self addChild:bg z:0];
     [self addChild:[SplashLayer node] z:1];

     // set the timer for the splash countdown
     [self schedule: @selector(tick:) interval:6.0];

     [self setupAudio];
    }
    return self;
}

-(void)setupAudio
{
    // instantiate the audio Manager in the appDel
    audioManager *audMan = [[audioManager alloc] init];
    HaloJumpAppDelegate *appDelegate = (HaloJumpAppDelegate *)[[UIApplication sharedApplication] delegate];
    [appDelegate setSndManager:audMan];
    [audMan release];
    //[appDelegate release];
}

// The tick method is a countdown that wait for the audioManager to preload it's content
-(void) tick: (ccTime) dt
{   
    // instantiate the AudioChoiceScene and set the audioManager
    AudioChoiceScene *acs = [AudioChoiceScene node];

    // transition
    [[Director sharedDirector] replaceScene:[FadeTransition transitionWithDuration:2.2f scene:acs]];
}
@end


// Layer empty at the moment
@implementation SplashLayer
-(id) init
{
    self = [super init];
    if(self != nil)
    {
    }
    return self;
}
@end

Any help/sugestions appreciated! anton
