i dont have in game sound

so I don't have in-game sound and when the match end then I get audio on the scoreboard any fix boys?

I'm too. Don't had this problem months ago.

Properly restart your computer - that is usually the fix for me.

A work of art is never finished, merely abandoned

Read about off all devices except you current audio device. It helps for me.
Plus update nvidia driver (read about problem with nvidia in old topics)

just update nvidia drivers and reboot pc
