[[SimpleAudioEngine sharedEngine] playEffect:@"*.wav"] breaks my app :(

I have Objects fling over the screen, when user taps an object - it explodes, using self-made animation(not CCAnimation or smt, self-made code for changing textures from array over time). It works fine.
I tried to add a simple sound on exlode:
```
#import "SimpleAudioEngine.h"
#import "CDAudionManager.h"
#import "CocosDenshion.h"
...
if (blowflag)
blowCount = blowCount +dt;

if (frame<NOfFrames)
  {
  frame = (blowCount/timePerFrame)
  }

     if (blowSoundNotPlayed)
         {
         [[SimpleAudioEngine sharedEngine] playEffect:@"explode.wav"]; //without this line everything works fine, no sound ofc.
         blowSoundNotPlayed=0;
         }
...
return frame;
```
As a result, i get no explode-animation(it works without that line), and my mic breaks, stops detecting blowsound. But sound works :D

Questions: Why it happens? Maybe i better use cacao instruments to play 1 freaking sound?

Thanks for any help

Not sure if this is any help or not, but with mine i preload the effect first:

//This is at the top of the init
[[SimpleAudioEngine sharedEngine] preloadEffect:@"woop.caf"];

[[SimpleAudioEngine sharedEngine] playEffect:@"woop.caf"];

After adding that line to init my MicBlowController breaks right away..

Didn't i tell i else trace my mic? :D

I'll also paste my MicController code, 'cos it seems to be important

- (void)viewDidLoad {
    [super viewDidLoad];

	NSURL *url = [NSURL fileURLWithPath:@"/dev/null"];

	NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys:
							  [NSNumber numberWithFloat: 44100.0],                 AVSampleRateKey,
							  [NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey,

As above try preloading it first.

If it crashes on preloading then it can't find the audio file. Check your resources

Besides it's good practice to preload the sound effects too.

```
Denshion::CDSoundEngine - mixer output rate set to 44100.00
```
```
CDSoundEngine - WARNING sample rate does not match mixer sample rate performance will not be optimal.
```
Maybe your .wav file isn't 44,100hz
(I don't know if iOS can only handle this sample rate, but I know it can handle 44,100hz)

Try to figure out what's the sample rate of the file you're trying to load, and convert it to 44,100hz if it's not already.

(I'm just guessing here, since I never tried to load a wav with different sample rate than that)

I tried 44100hz - didn't help.

Problem seems to be in Audio Session's management while playing & recording at the same time. If i use SimpleAudioEngine it tries to manage it himself and ignores what something should be recorded. If i use AVAudioPlayer i just don't get any sound, i don't know why yet.

Resolved, i'll post my code tomorrow.

thanks for ideas, everyone

#import "Controller.h"
#import "CDAudioManager.h"
#import "CocosDenshion.h"
#import "SimpleAudioEngine.h"

@implementation Controller

AVAudioPlayer *theAudio;

-(void) init: layer

{

	UInt32 sessionCategory = kAudioSessionCategory_PlayAndRecord;
	UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
	AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);
	AudioSessionSetProperty(kAudioSessionProperty_OverrideAudioRoute, sizeof(audioRouteOverride), &audioRouteOverride);

	AudioSessionSetActive(true);

	NSString *path = [[NSBundle mainBundle] pathForResource:@"bubble" ofType:@"wav"];
theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
[theAudio prepareToPlay];
	//[theAudio play];

...
}

-(void) playTheSound
{
			UInt32 sessionCategory = kAudioSessionCategory_PlayAndRecord;
			UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
			AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);
			AudioSessionSetProperty(kAudioSessionProperty_OverrideAudioRoute, sizeof(audioRouteOverride), &audioRouteOverride);

			AudioSessionSetActive(true);

			//NSString *path = [[NSBundle mainBundle] pathForResource:@"bubble" ofType:@"wav"];
		//	AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
			///		theAudio.delegate = self;
		//	[theAudio prepareToPlay];
			theAudio.volume=1;
		[theAudio play];
}

If i do it somehow else - or no sound is presented, or my mic is not working properly.
Hope it helps somebody :D

And you left the recording code with mic like the first code you put? I have a similar problem with a little twist. I'm playing in other scene a sound with SimpleAudioEngine and in other I detect the blow of the mic. When I start the scene with the mic after I played the scene with music doesn't work...on the iphone in simulator works just fine. :(

I'm reading the cook Audio Session Cookbook but ...I'm lost hehe

This part of the code is doing what I needed! :D

UInt32 sessionCategory = kAudioSessionCategory_PlayAndRecord;
	UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
	AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);
	AudioSessionSetProperty(kAudioSessionProperty_OverrideAudioRoute, sizeof(audioRouteOverride), &audioRouteOverride);

	AudioSessionSetActive(true);

Thank you!

Do you need to put these lines each time you play a sound ?

@Yohan85 - you never need those lines unless you are recording. Once the audio session is set to PlayAndRecord (set CDAudioManager mode to kAMM_PlayAndRecord in CocosDenshion) then the audio is rerouted to the in call speaker at the top of the phone. So you need to reroute every time you set the audio session to PlayAndRecord.
