(Redirected) Dell audio drivers doesn't load when the system is turned on for the first time after shutdown.

Dell audio drivers doesn't load when the system is turned on for the first time after the shutdown in Windows 10. I should restart the system everytime. So what I am doing is putting the system in sleep. in this way I don't need to shutdown and restart the system. It is Dell Inspiron N5559. Audio drivers are up to date and installed. Hardware working fine.
