Check the volume level: Ensure that the volume on your Surface Pro is not muted or turned down too low. You can check this by clicking on the speaker icon in the taskbar and adjusting the volume level.
Update the audio driver: Sometimes, outdated or corrupted audio drivers can cause issues with the speakers. You can update the audio driver by going to the Device Manager, finding the audio driver under “Sound, video and game controllers”, right-clicking on it, and selecting “Update driver”.
Run the Windows troubleshooter: Windows has a built-in troubleshooter that can help diagnose and fix common audio problems. To run the troubleshooter, go to Settings > Update & Security > Troubleshoot > Playing Audio.
Check for software updates: Ensure that your Surface Pro is running the latest version of Windows and that there are no pending software updates.
Check the audio settings: Make sure that the correct audio device is selected as the default playback device. You can check this by right-clicking on the speaker icon in the taskbar, selecting “Open Sound settings”, and checking the “Choose your output device” option.
If none of the above steps work, it may be best to take your Microsoft Surface Pro to an authorized repair center or contact Esmond Service Centre if your Microsoft Surface Device is out of warranty.
