I have something similar. I got mine after my first COVID infection. The infection was mild, but my sense of smell was gone for a week and i was left with a tinnitus
Huh, as I commented on the grandparent, I've also been getting it intermittently for very short durations each time. I also had the no-sense-of-smell-only Covid in 2021, but since the "tinnitus" thing really doesn't bother me much, I never thought much of it and can't say whether it started before or after my infection.
