    2.     Fix registry by copying the following entries from another available computer.

     

    a)     Boot in another available computer and press WIN + R to open a Run window.

    b)     Type in regedit and hit Enter.

    c)     Navigate to the following path:

     

    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}

     

    Note: there are several items in the same path, please select the one with the default data "Sound, video and game controllers".

     

    d)     Export the items to 1.reg file and copy to your computer.

    e)     Open Regedit Editor and import 1.reg file.

    f)      Restart the computer.

     

    3.     Boot in BIOS to check if Sound is turned on in Intergrated Device or LegacySelect Options.

     

    a)     Restart the computer and press F2 or Del to boot in BIOS.

    b)     Find Sound option and turn it on.

    c)     Save changes and restart.

     

    4.     There also might be related to hardware defect, you may contact hardware manufacturer for support.

     

    Hope this helps. Thanks.
