Because i had some problem playing small .wav file with MediaPlayer i switched to SoundPool. So far it seems it performing better than MediaPlayer but the problem i am having is the sound level, which should be 0.5 of system sound level.

i tried with

soundPool.play(currentSoundId, 0.5f, 0.5f, 1, 0, 1);

and it was still at the same sound level, i also tried with

int streamId = soundPool.play(currentSoundId, 1, 1, 1, 0, 1);
soundPool.setVolume(streamId, 0.5f, 0.5f);

and it was same level, any idea how to force to play it at specific volume? Its weird because it seems its not accepting any floats for sound i put in.

EDIT:

i initialize with following constructor

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)

 audioAttributes = new AudioAttributes.Builder()
 .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
 .setUsage(AudioAttributes.USAGE_GAME)
 .build();

 soundPool = new SoundPool.Builder()
 .setAudioAttributes(audioAttributes)
 .setMaxStreams(2)
 .build();
 else
 soundPool = new SoundPool(2, AudioManager.STREAM_MUSIC,0);
 

You should start using ExoPlayer, it has more rigid API then MediaPlayer and SoundPool
You can find it here, ExoPlayer.

It has setVolume(float) api
See more here

Is you are using old SoundPool constructor with AudioManager.STREAM_MUSIC stream or more relevant SoundPool.Builder ?
If Builder using, what AudioAttributes passed into initialization ?
