Overview
If you have problems with your mic not working or sounds not working, this guide will show you how to fix that by properly setting them up.
How to Fix the Input (mic) and Output (headset/speaker) Problems Within the game.
What you want to do is to go to your home screen with HLL open. You will want to:
1) Right click the home screen (no apps/shortcuts in the way)
2) Click on display settings
3) On the left side, go to sound
4) There you can see your default in/out-put devices, but scroll down all the way
5) You will see advanced sound options, click on it
6) You will see HLL in the apps section. From there, you can select specific inputs and outputs for HLL specifically.
If this does not work, then it will most likely be a problem outside the game. Ex: The mic is broken, etc.
