Fluid in ears: Sometimes people get fluid trapped behind the eardrum that causes such crackling. Sometimes it is related to allergies. I have had it for years and cannot get rid of it. If it bothers you, please visit your physician who can advise.

Air movement: As you open or close the Eustachian tubes between your throat & middle ear you can add or release pressure on the ear drum which may cause a sound. This happens with yawning, chewing & other movements that tense the levator palitini muscle which pulls the tube straight/open.
