Whenever I sleep my laptop I mean if I down the flap sound doesn't work, every time i have to restart my laptop for sound to make working.Fo instance right now sound is not working(since I closed the flap few minutes back.) so I check sound app and in output tab its showing Speakers Built-in Audiobut still I can't hear the output sound.I've even tried sudo alsa force-reload but still same problem.
