Not entirely too late, at least it helped me.
Been trying to find a solution for this same problem and was beginning to think a repair was needed.
Just to confirm...with a needle, after clearing out a clump of fluff sound now plays through both earphones of the 5 different headsets that wouldn't work before.
For anyone else trying to fix this problem either now or in the future, its at least worth a try.
