Set Volume on embed Player

Currently the only option to change the start volume is by using the code below in the embed code:

     kWidget.addReadyCallback(function( playerId ){
     var kdp = document.getElementById( playerId );
     // binds an event and namespces it to "myPluginName"
     kdp.kBind("doPlay", function( ){
         kdp.sendNotification("changeVolume", 0.1);

The value can be between 0 to 1, in the code above I set it to 0.1, example HTML page.
