Try these fixes in order
Select the correct sound output
Open Settings → System → Sound. Under Output, choose the actual headphones, speakers or monitor you want. Some screens and USB devices add extra audio outputs automatically.
Check both system and app volume
Open the Volume mixer and confirm the app is not muted independently. Test a system sound and another app to distinguish an application problem from the device output.
Try built-in diagnostics
Open the Get Help app and run Windows audio troubleshooting. Read the suggestions before approving changes, and restart the computer when instructed.
Check external devices and sound enhancements
For wired speakers, confirm cable placement and power. For Bluetooth headphones, verify connection and output choice. If a device supports audio enhancements, temporarily disable them to test whether they interfere.
Update drivers from trusted sources
Run Windows Update, including appropriate optional driver updates. If the problem began after an update, consult Microsoft or the computer maker before rolling back or reinstalling the driver. Do not download random driver “repair packs”.
Frequently asked questions
Why does sound play through my monitor instead of the laptop?
Windows may have selected HDMI/DisplayPort audio when an external display was connected.
