Mine just started to do this with the USB cable plugged in too. Even in bypass mode it’s just a noise generator & not usable. I need to have the USB for clock sync.

It doesn’t really make sense why considering that no audio is passing thru the USB cable & the unit is being powered by a power supply.

With a highest quality USB-C cable direct into a macbook this unit should be DEAD quiet. Never have I ever had any USB problem ever like this even with really inexpensive gear.

Are we sure there just isn’t a problem with the USB ports on these units?
