Mic Always Live

Hello All !

So i have set up X Split to push to talk mode. So when im recording games i have to push a button to talk as i have alot of back ground noise. I have set up the hot key, and it appeares to work, when i press the PTT button the Icon unmutes and records my voice (colourd bars appear when speaking). However, even when i am not pressing the PTT button the mic remains live and is picking up audio on a grayed out bar. Its as if the mic is just live all the time regardless of the PTT status. Any help ?
