The Mic mute switch on the headset mutes the mic and stops it picking up audio through the mic. It doesn't stop another software trying to access and use the mic though. Think of how you speakers work. Audio is still being played even if you turn them off. You just don't hear it.

Check ingame mic options and make sure it isn't broadcasting all the time or you are not using a push to talk key for other actions.
