android - AndEngine : Music isn't working properly -

i'm using following code in onscenetouchevent :

if(audiocontrolbutton.contains(pscenetouchevent.getx(), pscenetouchevent.gety())          && pscenetouchevent.getaction() == touchevent.action_down) {     togglevolume(); } 

and works fine, method invoking when has to. togglevolume() has implementation :

if(levelmusic.getvolume() != 0f) {     levelmusic.setvolume(0f); } else {      levelmusic.setvolume(100f); } 

all of condition seems work, issue comes here: if levelmusic.setvolume(0f) ivoked music volume disables should be, if levelmusic.setvolume(100f) invokes still can't hear music

note : i've tried pause() , resume() , it's not working well

my levelmusic variable:

music levelmusic; //field in scene class levelmusic = data.getlevelmusic(); levelmusic.play(); 

in onresourcesloadingfinished

edit : i've tried set value 60 instead of 100 , 0,9f(if max malue 1f), it's not working too

if have problem :

use levelmusic.setvolume(0.0f, 0.0f); // 0f wont work

so, whole method should looking this:

if(levelmusic.getvolume() != 0.0f) {     levelmusic.setvolume(0.0f, 0.0f); } else {      levelmusic.setvolume(1f); }
