Doorbell speaker constantly buzzes loudly

House was built 6 months ago. In the last month the doorbell speaker has started constantly buzzing. I opened a ticket with Lennar (home builder) and they said "this is normal with Ring doorbells." Obviously that's ridiculous. Something is clearly wrong somewhere and I want it fixed. A Google search returns thousands of hits with people having this same problem. Some say it's a wiring issue, some blame Ring. What do I do? I'm about to disconnect the Ring doorbell permanently.
