In Counter-Strike: Global Offensive, the CSGO sound becomes wrong. You can refer to the following to solve the problem:
1. It may be a game bug or an error in the game program. Try restarting the game and computer. If that doesn't work, you can uninstall and reinstall the game, open STEAM, select Manage and Uninstall from the gear on the right side of the CSGO main page, and then download the game again.
2. It may be that the game files are missing, so you can verify the integrity of the game. Open STEAM, click Properties on the CSGO main page gear, select the local file and verify the integrity of the game. If the file is missing, it will automatically reinstall the missing file for you, and finally restart the game.
