@fast-helmet-34582 Quite possibly there are two paths to ground. One being the ground on the Rodecaster and the other through USB to the computer ground. If they are both in the same power strip I would not expect a ground loop to happen. You could temporarily try a 2-prong adapter on the Rodecaster and if that fixes it you might get a Hum-X for a permanent solution. Also they have USB-C ground lifters and that is another possibility.
