[2019] VoIP won't work for me

So I haven't played in a few months, me and a few mates came back today and whenever I try talk in game it doesn't work. Like the little mic icon doesn't show up, and my friends can't hear me in-game.

I checked my keybinds in game and it's on CapsLock as it should be. I verified my game files and that didn't fix anything.

Anyone know what's going on?
