I am aiming to play and loop multiple sounds at the same time using the soundpool class in java.  I am new at this and it appears I am not able to loop more than one sound at at time.  I can play multiple sounds at the same time but when i set the loop parameter to anything other than zero I am limited to only being able to play one sound at a time.  

Here is the code.

package com.example.poolsoundsample;

import android.media.AudioManager;
import android.media.SoundPool;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {

	Button button1;
	SoundPool sp;
	
	Button button2;
	SoundPool sp2;

	int pianoa = 0;
	int pianob = 0;
	
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		sp = new SoundPool(99, AudioManager.STREAM_MUSIC,0);
		pianoa = sp.load(this, R.raw.bassloop2, 1);
		
		 button1 = (Button) findViewById(R.id.button1);
	        button1.setOnClickListener(ButtonClickListener);
		
	        sp2 = new SoundPool(99, AudioManager.STREAM_MUSIC,0);
			pianob = sp2.load(this, R.raw.bassloop3, 1);
			
			 button2 = (Button) findViewById(R.id.button2);
		        button2.setOnClickListener(ButtonClickListener);
	}

	
	private OnClickListener ButtonClickListener = new OnClickListener() {

		@Override
		public void onClick(View v) {
			// TODO Auto-generated method stub
			//if (sound1 != 0)
			//	sp.play(sound1, 1, 1, 0, 0, 1);	
			switch(v.getId()) {
////////////////////////////////Start button 1//////////////////////////
			        case R.id.button1:
				        	if (pianoa != 0){
				        		sp2.play(pianob, 1, 1, 0, -1, 1);}
			        		break;
			        case R.id.button2:
			        	if (pianob != 0){
			        		sp2.play(pianob, 1, 1, 0, -1, 1);}
		        		break;
							}
		}
	};
	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}
	}

Do you think I have to do them in different threads?  Is it possible to loop multiple sound pools at once?

Hello ForLoop5. You only require one sound pool to do this. You have created a pool with 99 streams, so it could potentially play 99 sounds simultaneously. You can load both sounds into the same pool and play them looping or otherwise in the same pool.
