Hi NickkToast,
Thank you for reaching out Microsoft Community. We apologize for the inconvenience this has caused you.
Can you tell us what is the current OS version of your Surface device? Is this with Intel Processor? Kindly click this link : https://support.microsoft.com/en-us/help/13443/windows-which-version-am-i-running to check the current OS version of y our Surface device.
Once done, please include it in your reply and follow the steps below.
Open Device Manager
Expand Audio Inputs and Outputs
Right-click on drivers available and select uninstall device. Once uninstalled, kindly restart your Surface to reinstall the drivers back and kindly download this in-place upgrade. Downloading the tool won't delete any files nor the applications you already installed on your Surface. If the issue with the audio is due to corrupted drivers, downloading the tool will repair and fix it. Just click Download Tool Now and hit Next once "Upgrade This PC" appears.
If this helps, feel free to mark this post as an answer. Otherwise, don't hesitate to respond to this thread if you need further assistance.
Kind Regards,
