Hello, thank you for reaching out to Microsoft Q&A.
- May I please know the list of audio drivers installed on your computer?
- Open the Device Manager (Click Windows + X key),
- Expand the arrow next to Sound, video, and game controllers.
- If you see Realtek (R) in the lists, right-click the device and select Uninstall, then select the Attempt to remove the driver for this device check box, and then select Uninstall.
- Once uninstalled, restart your computer and check your speakers. (Click Power> Restart)
If it still doesn't work, type msinfo and click Enter.
Post a screenshot of the resulting dialog box.
