Having a stupid moment with microphone settings

[PsiFox]

Ok must have ticked or unticked something but cannot remember what.

I was always able to disable the whilst working in windows but it would work for chat and in games with a PTT(press to talk).

Can someone remind me how I get back to this pleasant situation again.

Thanks
