android - SoundPool not playing sounds -

-

i made soundmanager class uses soundpool functions in order loop specific sound, can't figure out why isn't playing sound.

public class soundmanager { private  soundpool msoundpool;  private  hashmap<integer, integer> 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<integer, integer>();       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);  }  public void playloopedsound(int index) {       int streamvolume = maudiomanager.getstreamvolume(audiomanager.stream_music);       msoundpool.play(msoundpoolmap.get(index), streamvolume, streamvolume, 1, -1, 1f);  }

}

this class being called activity via:

private soundmanager msoundmanager; msoundmanager = new soundmanager(); msoundmanager.initsounds(getbasecontext()); msoundmanager.addsound(1, r.raw.sound); msoundmanager.playsound(1);

apparently doesn't work oncreate activity calling when event happen (intents / keypress) seems work
