Hi,
If it is a laptop or desktop, if possible, could you provide the laptop model or your desktop configuration? To check, access msinfor32.exe in the search bar, take a screenshot and post it here.
Access the device manager and check if the Realtek or High Definition Sound driver is installed or if there are any errors in the "Sound, video and game controllers" tab.
If the driver is installed and there are no errors, access the start menu > settings > system > troubleshoot > other troubleshooting > sound > run.
Thanks
