How do I suppress all audio output when recording with a mic

:)

 

Headset Micorphone Volume Slider issue.


I was trying to skype a fellow mate when he said he couldent hear me. So i went to my recording devices and saw that my microphone volume was at 0. I tried to turn it up but it just went back to 0. Now its Glitching out between 0 and 5... No idea how to fix this. I plugged the headset into a different USB and nothing. Plugged my webcam in and the same thing happened....

 

Camera and Microphone will not turn on

IT SAYS TO TURN CAMERA ON AND MICORPHONE

 

Cortana pronounce

cortana speaks fine otherwise. she pronounces my name and i click 'that's wrong' she then says to speak it into the micorphone after that she says it again this time she says it correct so i click 'that's right' but then she goes back to pronouncing it
the wrong way again /
