After I used Skype and made a call, ever since then my sound doesn’t work , but I can use headphones and they work. I have a visual land

There are many answers to this question, as I will list below. The speaker could be faultyA(some) wires can be loose or cut in between the speaker and the CPUSome apps will only support headphonesHigh volumes on a some speakers may damage the speaker temporary or permantly Here are some ways the the problem can be fixed, or resolved. Doing a soft resetDoing a hard resetIf the tablet froze unplug it untill it dies, then turn it back on (this my take form a minute to a week, matering on you screen brightness or/and how much battery is left)Push the reset button If all fails, Bring it to a servive guy and see how much the repairs will cost( if the repairs are more expensive then the tablet itself, get a new one)Find a speaker that you can mount on the back of the tablet that connects using a 3.5mm headphone port or a speaker with an adapter for a 3.5mm headphone jack(only recommended if you give up) Find an awesome way to destroy it (for ex. mounting it with ropes on 2 of your cars and ripping it to pieces or do some target practice and shoot it with something like a 22)
