allow/deny message not showing on ie 10

[tejkiransharma]

Hi,

I am using jwagener/recorder.js for recording that is working fine on ie 9 and ie 11 but for ie ver. 10 its not working. when my recording section start it does not prompt for microphone setting allow/deny message.
Sometime when we clear browser history number of times then it prompt once for that massage.

Initialization...
Recorder.initialize({
swfSrc: BASE_URL + "/Scripts/flashrecorder.swf"
});

Recording...
Recorder.record({
start: function () {
// here our code is put. this part of section does not execute
}
});

Please suggest any solution to run this code on ie 10
