[HowTo] Mute Your Microphone + Deafen

Step One:
Make sure you are in a Voice Channel.

Step Two:
Find the Microphone and Headset icons. They should be placed next to each other below the Voice Channels.

Step Three:
In the image above, the icons have a red slash through them, meaning I have deafened (I cannot hear sound in the Voice Channel I am currently in) and I have muted my microphone (If I speak, nobody in the Voice Channel can hear me.)
Below is an image of what it looks like if you are unmuted and have undeafened everyone.
Please be aware this applies to both Downloaded and Website platforms of Discord.
