Sorry, you stuck with this so far. I think for most people, it fades away over the years. Luckily my episode of noise faded and was probably triggered by some lifestyle change at the beginning of the pandemic. However, I also have visual snow and think my brain just isn't very good at hiding its inner workings from me, may be just a matter of attention, rather than some "somatic" defect. I think the fact, you had a period of absence is promising and worth exploring and playing around.
