Unmute from the speaker icon in your os.

I have a nextbook premium 8 SE tablet. What ever screen I am in even when it is turning on it has two horizonial lines.

Since you did not give us the model, it is impossible to tell you exactly how to do this.
You need to get to Settings/Sounds/Notifications or a similar menu description.
