Disable Mute in IWS or WDE

There any way to disable the mute button in WDE 8.5?

SDK by way of a custom module ?!?

Thanks Tambo,
I think that would be the only option, because I find no existing option of WDE to do that function.
Thank you

There is no option such like that at this moment. You can achieve that through customization or open a feature request.
