Chello, thank you for your post about this annoying USB noise. Very informative!
I have the same issue with my Pa5X and ModX connected to a mixer and the MODX by USB. When I disconnect the MODX USB connector the noise is gone. Can the unbalanced audio outputs of the MODX in combination with USB also be a source of noise?
I wasn't aware of the existence of USB-isolators. I'm really curious if they work well. Don't know if there are any disadvantages using USB-isolators.
Worth investigating!
