[TIMOB-2129] Set Audio player volume up down

Hi,

I am trying to create live radio streaming iPhone application , streaming run succesfully but i don't understand how to set audioplayer's volume up and down in application.In Doc also no volume property or method is given for audioplayer. I am trying below code and logic to set volume but it won't set the volume.

var a = Ti.Media.volume;

plus_vol.addEventListener('click',function()
{ if (a < 1)
{

a += 0.1;
Ti.Media.volume = a;
alert(Ti.Media.volume);

} }); min_vol.addEventListener('click',function()
{

if (a > 0)
{
    if (a < 0.1)
     {
        a = 0;
        Ti.Media.volume = a;
            alert(Ti.Media.volume);
      }
    else
     {
        a -= 0.1;
        Ti.Media.volume = a;
            alert(Ti.Media.volume);
     }
}

}); Note : Ti.Media.volume value is 1 but it will not change after the code implementation.

Please tell me if its possible to set live streaming volume in app. Thanks in advance.
