I'm a computer repair technician for the Cumberland County Board of Education in Crossville, TN. I'm from Moulton, AL and I attended Auburn University in Auburn, AL. I studied Electrical/Computer Engineering and worked at the Auburn University Bookstore in the Technology Department as a sales associate and assisted the main repair technician with repairs.
"Why is audio not playing from the speakers?"に関する回答There's probably a small hardware switch in the headphone port (like in many Apple devices) that's stuck. When there isn't anything plugged into the port the switch should be protruding ever so slightly. If you have a flashlight handy you can peek inside it and see if you see it. If not, try plugging in a pair of headphones a couple of times to see if it unjams it. If that doesn't work, it could be a software problem or a deeper hardware problem.
