Hey @Aschenherz , last i recalled, I think @makeyourownluck mentioned her 'venomous hum' showing up occasionally, once and while. That was a while ago though. It's possible it's gone now.
For what it's worth, during my onset I had a low hum buzzing sound too. It sounded like lightsabers from star wars. It went away after a month or 2. Hopefully it'll be the same for you too.
