I have no idea what happened. I used to be able to go to YouTube, watch videos and be able to hear the sound through my laptop speakers. But now I hear nothing. The sound bar thing, to increase and decrease the sound, lower right side sound icon, when I tap it, I see the slider but it's not bold, it's grey out of not able toto use, not enabled. When I use the Get Help app, I doesn't ask me the right question or allow me to ask my specific question. My question would be something like, please help me get sound to come out of my laptop speakers, where are my laptop speakers, why do I have to always connect an audio device to hear sound from my laptop? Those would be my questions. Get Help continues to only ask me to connect an audio device before it can assist me. when I do that, it does continue to check my sound capability through that connected device and yes That works, I heard the sound through that audio device but that's not what I'm interested in, I know that work. I would really like to learn what may have happened and some suggestions to fix my specific problem. Any savvy outstanding techs out there who already know the possible answer to my issue and so confident that you are so sure you can narrow it down to a few suggestions and for sure fix, I'd be so delighted to learn from you. Thanks Tech guys and gals, your help is always invaluable. I hope I'm using that correctly. I am trying to say, your help, service and technical savvy abilities are very valuable, priceless
