Audio is Muted or Distorted ¶ 

You have trouble with the audio on your tablet due to material stuck in your audio jack or because your audio jack is loose

Dirty Headphone Jack ¶ 

If your headphone jack has accumulated some dirt or various debris, it may affect the functionality of the device. Insert a Q-tip carefully in the headphone jack in order to clean it. Or, if you have an air can, simply use that to blow out anything that has accumulated inside the headphone jack. Our guide can be found here:

Loose Headphone Jack ¶ 

Your headphone jack may have loosened from continued use. Test audio through speakers and then through headphones. If the audio is exclusively distorted through headphones, the headphone jack or headphones themselves could be faulty. Try different headphones if headphones are faulty or make sure the audio jack is fully inserted in the tablet.
