Get Sound size Of Android Device

hello everyone..

I have developed game and i have given option for setting volume size. This sound settings affects my game sound only. This does not relate with my android device sound.

But i just want to check one condition that whether my device sound is set to mute or not. But i am not getting the way to check this.

So if anyone knows to detect android sound status then please let me know.

Thanks in advance for your support and help..
