iOS native + volume

Hi,

I've been trying to develop a radio app for iOS and Android (native).

I use the Ext.Audio to play the stream but I'm not able to change the volume, either With Ext.Audio or the Ext.device.Media singleton.

Surprisingly, Cordova implements a setVolume method, whereas Ext.device.Media doesnt.

Could you help me pls ? Remember, it's a native app, not Html5

Thx
