I agree it shouldn't make any noise, but mine makes a buzzing sound too, and yes it is definitely an XG1v4. I had it swapped out and the new one seemed ok for a while, but now this one does the same. I'm not going to a store during the pandemic and the last time I was at the nearest store they didn't have the box for my area (wrong video headend Arris or Cisco I guess). It's a pain to do it by mail because I have to go to a UPS store to return it, plus if I already swapped it and many other people have the same complaint in this and other threads, what's really going on with them?
