Fix sound RCA Tablet

Solution
Did you check if the volume is muted maybe? Did you try rebooting the device? If neither of those did anything, it may be a physical issue with the speaker that needs to be repaired. You can try a factory reset to defaults, that will wipe all the data on the tablet and will reset it like it was new.
