realtek error code 10 vista i have no sound please help
i install realtek driver and restart the computer but sound never works

First before you do anything wild, just try a restart and see if this helps you. If this doesn't help you then what you can do is go ahead and uninstall your realtek driver, divers usually have tendency to fail sometimes that's common. So just uninstall and find the same realtek driver with the same name on the realtek website and re-download that driver. Im sure this should get you up and working, have a nice day!
