Android Soundboard wont play sounds
<p>I have created a soundboard and everytime i click on a button to play a certain sound nothing happens. Here is the sound manager code:</p>

<pre><code>package com.androidbook.ufgsoundboard;

import java.util.HashMap;

import android.app.Activity;
import android.content.Context;
import android.media.AudioManager;
import android.media.SoundPool;



public class SoundManager extends Activity {

    private  SoundPool mSoundPool; 
    private  HashMap&lt;Integer, Integer&gt; mSoundPoolMap; 
    private  AudioManager  mAudioManager;
    private  Context mContext;


    public SoundManager()
    {

    }

    public void initSounds(Context theContext) { 
         mContext = theContext;
         mSoundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0); 
         mSoundPoolMap = new HashMap&lt;Integer, Integer&gt;(); 
         mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);         
    } 

    public void addSound(int Index,int SoundID)
    {
        mSoundPoolMap.put(Index, mSoundPool.load(mContext, SoundID, 1));

    }

    public void playSound(int index) { 

         int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
         mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f); 
    }

}
