I think I can sort of relate to what you are describing, in my most affected ear, the one with heavyness/fullness feeling, the unmaskable constant tinnitus tone sort of seems to "cycle" it changes in it's tone on constant, regular basis, but is not linked to heart rate or anything like that. It basically feels like something "dead" or "wounded" is thrashing around in your ear, and no amount of supplements you throw at it will calm it.
