Laptop Audio not working without a headset

Select the Surface’s built-in speakers as the output device, then run Surface diagnostics and updates; if the speakers remain silent while the headset works, submit an in-warranty service request.

1. Select and test the built-in speakers

1. Unplug the headset and disconnect any Bluetooth speakers, docks, monitors, or other audio accessories.
2. Open Start → Settings → System → Sound.
3. Under Output → Choose where to play sound, select Speakers or the Surface’s built-in audio device—not Headphones, Bluetooth, HDMI, or a dock.
4. Raise the output volume and confirm it is not muted.
5. Play a Windows notification or video to test it.
6. Check that a case, screen protector, or decal is not covering the speaker openings.

Microsoft’s Surface audio procedure identifies output selection, obstructions, updates, and driver repair as the relevant checks for built-in sound problems.^1^

2. Run Surface diagnostics and install updates

1. Open Start, search for Surface, and open the Surface app.
2. Expand Help & support.
3. Select Check for updates, install everything offered by Windows Update, and restart the laptop.
4. Return to the Surface app and select Get help, then describe the built-in-speaker problem.
5. Search Start for:
   • Surface Repair Tool on 2026 and later models, or
   • Surface Diagnostic Toolkit on earlier supported models.
6. Run the tool and follow its on-screen instructions.^2^

If diagnostics do not restore sound, use Microsoft’s Surface-specific driver procedure rather than downloading a generic Realtek driver intended for another laptop brand. The Surface audio guidance supports manually updating or reinstalling the drivers for the exact Surface model.^1^

3. Use the warranty if the speakers remain silent

For a personally owned Surface:

1. Go to Microsoft account devices.
2. Sign in with the Microsoft account associated with the Surface.
3. If it is absent, select Register device.
4. Select the Surface and review its warranty status.
5. Select Next and follow the prompts to create a service order and shipping label, or choose an available authorized in-person provider.
6. Back up your files before service; Microsoft recommends backing up and erasing the device before returning it.^3^

If this is an employer-owned Surface, contact the organization’s IT helpdesk instead; business devices use separate service options.^2^

Do not post an email address, telephone number, serial number, or account details publicly. Remove the personal contact information from the question if editing is available.
