No Audio Fix
If your game has no audio or has partial audio meaning that some sections of the game have audio while cutscenes or different elements do not have any audio, it means that your audio driver is misconfigured or is outdated. Try updating your audio driver however if the problem still persists, disable Windows Sonic for Headphones. This has been working for a lot of players around the world.
You can also check the configuration of your sound in the Control Panel to ensure that the correct settings are in place. Sometimes the audio setting might be out of place which might be causing you to hear only partial sounds of the game. Checking the audio control panel and updating your audio driver will fix most of your audio problems automatically.
