I cannot hear anything out of the speakers on my iPad.

Have you tried to use earbuds or headphones?

If you already followed (to no avail) all the steps provided here:--> If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support, contact Apple Support directly, using this link:--> Get Support , or make an appointment and have your device inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> Apple – Location Selector

After checking it out, they'll give you all the available options.
