Soft music/sound in ear when lying down.

Hi, I have right lower jaw with swelling in the jaw for more than 2 months. Went to different specialists and no answers yet. Went to ENT and had an Endo. No infection in sinus and ear. I have clogged ears for more than 2months. No wax or infection in the ear. Dentist told me to extract upper wisdom tooth and did it 4 weeks back. Still have the same symptoms. Referred me to tmj specialist. They said I have tmjd. Since last 5 days, I hear some music or soft sound like opella whenever I lie down. It will be for 5 minutes or so. If I change to my sides, it will go off. If I lay down straight on my back, I will hear it again. Is this because of my ears clogged for long time? I still have sore pain and clogged ears. I checked my ears last week too with my regular physician. No infection or fluid in the ear. What could be the reason for this sound hearing? Is it related to tmjd? I also have sore pain on top of the head that side. It hurts to touch under the ear in the lower jaw and head.
