Elgato sound not working?

Never worked for me neither, i'd recommend hooking up an external software and start recording both at the same time or start recording the video 3 seconds after then edit it out
 


What's an audio controller?
 


It has quite a few;

AMD High Definintion Audio Device
Blue Snowball
Game Capture HD
High Definition Audio Device
Logitech G633 Gaming Headset
 
It's likely the mic and headphone drivers are causing issues. Firstly disable Elgato sound capture then check the other drivers are up to date in that section, reboot and see if you get audio.

It is fairly complicated and unless you know what you are doing you are going to find it tricky tbh.
 


Still not got any audio when I record 🙁
