I'm sorry to hear about the buzzing noise issue with your PPC Active Return EV 01–5 – U/U entry series box. That sounds quite disruptive, especially with it happening every morning. Let's see if we can figure out what's going on and find a solution.

Possible Causes and Solutions
Power Supply Issues: The buzzing noise might be related to the power supply. Ensure that the power connections are secure and that the power supply is functioning correctly.
Signal Interference: Sometimes, signal interference can cause buzzing noises. Check if there are any nearby devices that might be causing interference.
Faulty Equipment: The box itself might be faulty. If possible, try to get a replacement or have it inspected by a professional.
Steps to Troubleshoot
Check Connections: Make sure all cables and connections are secure. Loose connections can sometimes cause buzzing noises.
Restart the Device: Try unplugging the box for a few minutes and then plugging it back in. This can sometimes reset the device and resolve the issue.
Inspect for Damage: Look for any visible signs of damage on the box. If you see anything unusual. 

If all this does not help please let us know.

This SUPER helpful advice and I’m going to wait until tomorrow morning to try your recommendations “while” it’s making noises.  Thankfully it’s Old Faithful regular in its daily noise making/timing.   I will report back, because if that doesn’t remedy I have no clue how to “describe” my problem to get through the automated customer service to speak to a live human.  Really appreciate your prompt response here.

Good morning!  Followed your excellent suggestions, and the noise definitely stops when I unplug it!  The space inside the "breaker box" is small enough that it's still hard to tell 100% if the actual noise comes from the block that I'm plugging in or the white PPC Active return box that all the cables attach to, but my money is on the block plug itself, which I would assume needs to be replaced? (this equipment is at least 13 years old?)  I unplugged (enjoyed the silence!!!), waited 5 minutes, and the second I plugged it back in the buzzing noise started up.  (can I post video, and would that help?)  Now the million dollar question, is how [Edited: "Language"] to I reach someone to schedule a home visit from a human Xfinity technician, and to explain my problem so that they show up with the needed equipment to repair/replace on the first visit?  I have had no luck navigating the customer service options via phone or chat... I just keep getting the AI loop and it asks me if I want help troubleshooting.  I don't know the "right words" to describe my issue, and technically my service is still working.  (and where we live, if it's not working, we don't have strong enough cell service to get online to try and contact xFinity via the app... nasty little Catch-22)  I'm truly grateful for your help here.  How can I schedule an appointment for someone to come replace this faulty/noisy block plug?

Good morning!

Thank you for following the suggestions and providing such detailed feedback. I can understand how frustrating it must be to deal with this persistent noise, especially when it's difficult to pinpoint the exact source. Given that the equipment is over 13 years old, it does sound like the block plug might need to be replaced.
