Try this Windows 11 path first:
- Check whether the built-in devices are detected.
- Select Start, type Device Manager, and open it.
- Expand Sound, video and game controllers.
- If the audio device appears, right-click it and select Enable device if that option is available.
- If it does not appear, select View > Show hidden devices, then Action > Scan for hardware changes.
- Verify the correct output device is selected.
- Go to Start > Settings > System > Sound.
- In Output, select the device to use for playback. Selecting it also sets it as the default output device.
- Verify the correct input device is selected and test it.
- In Start > Settings > System > Sound, under Input, select the microphone to use.
- Use Start test, speak normally, then Stop test and Play to check the recording.
- Adjust the Input volume slider if needed.
- Make sure devices are not muted or disabled.
- Right-click the Speakers icon on the taskbar and open Volume mixer.
- Confirm nothing is muted.
- In Settings > System > Sound, open the device properties for both input and output devices and make sure they are not disabled.
- Restart the PC.
- Select Start > Power > Restart.
- After restart, check whether the speaker and microphone reappear.
- If the devices are still missing, reinstall the audio drivers.
- In Device Manager, expand Sound, video and game controllers.
- Right-click each audio device and select Uninstall device.
- If prompted, select the option to remove or delete the driver for that device.
- Restart the computer.
- If Windows does not reinstall the devices automatically, return to Device Manager, right-click Sound, video and game controllers, and select Scan for hardware changes.
- Then right-click the audio driver and select Update driver.
- Install updates.
- Go to Start > Settings > Windows Update > Check for updates.
- Install available updates, then restart.
If this is a Surface device, also check the Surface app under Help & support and install available driver or firmware updates. If built-in audio or microphone still fails on Surface, manually reinstall the Surface drivers and firmware package for that model.
