Open Start → Settings → System → Sound, select your Surface speakers under Output, turn the volume up, and make sure sound is not muted.
1. Select and unmute the speakers
- Open Start → Settings → System → Sound.
- Under Output:
- On Windows 11, expand Choose where to play sound.
- Select the built-in Surface speakers.
- Raise the volume slider and ensure the mute button is off.
- Play a video or system sound to test it.
You can also press the keyboard’s volume-up key. The keyboard and taskbar volume controls change the same Surface volume setting.^1^
2. If no speakers appear under Output
If Sound settings says No output device found, run the automated audio repair:
- Open Start and search for Get Help.
- Open it and search for audio troubleshooter.
- Run the troubleshooter and apply any recommended fix.
- Restart the Surface and test the speakers again.
Microsoft recommends the Get Help audio troubleshooter for Surface sound problems.^1^
3. Install Surface audio-driver and firmware updates
- Connect the Surface to power and the internet.
- Open the Surface app.
- Expand Help & support and check the update status.
- Select Check for updates if offered.
- In Windows Update, install all available updates.
- Search Windows for View optional updates and install any driver updates whose names include Surface.
- Restart the laptop.
Microsoft recommends keeping the battery at least 40% charged and leaving the Surface connected to power while updates install.^2^
4. If the X remains
Perform a full Surface shutdown:
- Select Start → Power → Shut down.
- Wait for it to turn off.
- Press and hold the physical power button for 20 seconds. Continue holding if the Surface logo appears early, until it appears again.
- Sign in and test the sound.^1^
If Windows still cannot find an output device, install the driver and firmware package made specifically for the exact Surface Laptop or Surface Book model. Find the model in the Surface app, then use Microsoft’s Surface driver page to select that model and install its package.^2^
Avoid using audio drivers intended for another computer brand or Surface model. If the correct Surface package does not restore the audio device, the remaining supported options are Surface service or hardware inspection.^1^
