What you want to ask is why there is no sound in cg? The reason is the problem of game setting and driving.

1, game settings: First of all, you need to check whether sound effects or music are turned off in the game settings. If so, you can try to turn on the sound effect or music again.

2. Driver problem: If the sound effect or music can't be played, it is because there is something wrong with the sound card driver of the computer. You can update the sound card driver of your computer to the latest version, or uninstall and reinstall the sound card driver.
