As title says. Sound shows as mute. Cannot undo or change with keyboard. In control panel no sound devices show up. In device manager Realtek HD audio is missing. Have tried to download the driver separately but I just get "Sony Packaging Manager extracting" then nothing come up after. In dxdiag it says no sound card found.
