Audio issues on Windows are more common than you might think. When there’s no audio coming from your computer, the Device Manager may throw error code 52 and alert you there’s no audio device installed. Try restarting your computer, and check if you notice any changes. If error code 52 persists, follow the troubleshooting solutions below.
