Can't hear sound Android Simulator Mac - android

I can't hear any sound in my Android Simulator in my Mac. Some times, verily little time I can hear it. I give you my code of my Sound Manager. But i think its configuration problems
I copy the code from a page that they said it works. And i already try about 5 different codes and none works. My sound are in WAV game: 100k menu 800k
Thanks

Basically, you have to set a flag in the config settings to tell it what kind of audio to output, and what device. It's a pain. I wrote about it here:
http://www.banane.com/2012/01/11/joy-of-android-playing-sound/
That worked on my old MacBook. Just upgraded to a Mac Air and the solution has changed, not sure, but -audio is the solution now. I'll post here when I get it working.

I SOLVED IT,
Just re-install all the eclipse and SDK. I try in another computer and works fine. The same code

SoundManager, how to stop sound playing

I use simple SoundManager for play sounds from sounpool. My problem is, sound not stop playing when I exit from app, even I use mySound.release();.
Otherwise, everything works as it should, here is my code.
import android.content.Context;
import android.media.AudioManager;
import android.media.SoundPool;
public class SoundManager {
private Context pContext;
private SoundPool mySound;
private float rate = 1.0f;
private float masterVolume = 1.0f;
private float leftVolume = 1.0f;
private float rightVolume = 1.0f;
private float balance = 0.5f;
// Constructor, setup the audio manager and store the app context
public SoundManager(Context appContext)
{
mySound = new SoundPool(16, AudioManager.STREAM_MUSIC, 100);
pContext = appContext;
}
// Load up a sound and return the id
public int load(int sound_id)
{
return mySound.load(pContext, sound_id, 1);
}
// Play a sound
public void play(int sound_id)
{
mySound.play(sound_id, leftVolume, rightVolume, 1, 0, rate);
}
// Set volume values based on existing balance value
public void setVolume(float vol)
{
masterVolume = vol;
if(balance < 1.0f)
{
leftVolume = masterVolume;
rightVolume = masterVolume * balance;
}
else
{
rightVolume = masterVolume;
leftVolume = masterVolume * ( 2.0f - balance );
}
}
public void unloadAll()
{
mySound.release();
}
}
The method play() return a int StreamId. You need to keep this StreamId on a variable and to call the stop method. For example:
Declare a Stream Id variable:
private int mStreamId;
Then, keep it when you start a new sound stream:
// Play a sound
public void play(int sound_id)
{
mStreamId = mySound.play(sound_id, leftVolume, rightVolume, 1, 0, rate);
}
So you can stop it doing:
mySound.stop(mStreamId);
Now you can stop your sound stream on the activities events onStop, onPause or where you want.
EDIT:
The best way to release your SoundPool resource is call release and set the reference to null after you stop playing the sound. For example:
#Override
protected void onPause() {
super.onPause();
mSoundManager.unloadAll();
}
On your SoundManager, change your unloadAll method to:
public void unloadAll()
{
mySound.release();
mySound = null;
}
Note the following:
onPause – is always called when the activity is about to go into the
background.
release: releases all the resources used by the SoundPool
object null: this SoundPool object can no longer be used (like #DanXPrado
said) so set it to null to help the Garbage Collector identify it as
reclaimable.
For more details, see this tutorial about SoundPool.
Hope this helps.

Delay in playing sound [duplicate]

I'm currently facing an issue with my android game. Normally when calling SoundPool.play() the function needs about 0.003 seconds to finish, but sometimes it takes 0.2 seconds which makes my game stutter. where could his anomaly come from?
thanks to Tim, using a Thread for playing seemed to workaround the problem successfully.

Level selector using andEngine. Every thing is black?

I started working on AndEngine and I have learnt a lot but i am stuck in creating levels selector for my game. I know this is something to do with getTextureManager() as i went through this when i am trying to attach ITextureRegion to my sprite object, that i solved but this time i am going nowhere for last day.

FYI, this code belongs to code bundle in Android game development using AndEngine cookbook.
I have edited few variables like font and engine , but i have't changed the logic or flow of program.
Now when I run this I get the below screen
Alright i solved my problem, its was the padding i was using, it should't be there.
try {
mBitmapTextureAtlas.build(new BlackPawnTextureAtlasBuilder<IBitmapTextureAtlasSource, BitmapTextureAtlas>(0, 1, 1));
mBitmapTextureAtlas.load();
} catch (TextureAtlasBuilderException e) {
Log.e("", ""+e);
}
it should be
try {
mBitmapTextureAtlas.build(new BlackPawnTextureAtlasBuilder<IBitmapTextureAtlasSource, BitmapTextureAtlas>(0, 0, 0));
mBitmapTextureAtlas.load();
} catch (TextureAtlasBuilderException e) {
Log.e("", ""+e);

how to stop different music files overlaping using soundpoll in android

hai i am doing one game here i need to display 100's of images into gallery,at the same time in wich image is in view that time i need to play that image related sound, i treid using sounpool for music play.i played sound correcltly but my prblem is in gallery scroling time when i move 1 image to 2 image that time both sounds 1 image,2 image related sounds are plying that time.how to solve that problem please any one suggest me..

i tried using mediaplyer its working good.but here each sound i need to set one mediaplyer object.in my app i need play some 100'of sounds.so is there any alternative solutoin please suggest me..
If you were using mediaplayer can could have easily stopped it using mp.isplaying() then do something.
But even i had the same issue i can suggest you one thing:
add a flag there and then you can check it the flag=true do something else do something
Ex: sound1 = mSoundPool.load(this, R.raw.abc, 1);
mSoundPool.play(sound1, 1, 1, 1, time - 1, 1);
loaded = true;
Now for the flag u can do like this
if(loaded == true)
{
mSoundPool.stop(sound1);
}
you can try this.

Android SoundPool.play() sometimes lags

I'm currently facing an issue with my android game. Normally when calling SoundPool.play() the function needs about 0.003 seconds to finish, but sometimes it takes 0.2 seconds which makes my game stutter. where could his anomaly come from?
thanks to Tim, using a Thread for playing seemed to workaround the problem successfully.
