Not with Zoloft, but I have had a similar experience.
I developed tinnitus as a consequence of an adverse reaction to levothyroxine. Oddly though, when I transitioned from it to an alternative, at first, my tinnitus went absolutely mental - impossible to mask without damaging my hearing from the amplitude of an external source required.
I experimented on myself and it was definitely the loss of the levothyroxine that made it worse, even though it caused it in the first place?!?!? It has taken more than 12 months, but it has reduced to a level below the severity of before I stopped levothyroxine.
