My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
Step 1: Right-click the sound icon in the taskbar located at the bottom right of the screen and select Playback Devices from the ensuing context menu.
Step 2: Select the current playback device in use and by default it should be the speakers. Double-click on it to open its properties window.
Step 3: Got to Advanced section and change the bit rate to either of the following - 24bit/44100 Hz or 24bit/192000Hz - depending on the speaker configuration.
If the issue is still unresolved, you can try another method for restoring sound:
Step 1: Launch Start Menu, search for Device Manager and then launch it.
Step 2: Expand Sound and audio devices.
Step 3: Right-click on the current sound driver and choose uninstall.
Step 4: Finally, click on Scan for hardware changes and the updated driver will be automatically installed.
Your computer speakers should now be able to play sound normally now. Let me know the results please.
