When I run the automatic setup for my receiver I get a loud clacking snapping noise from the tone off the walls in the corners it seems. It is like a ringing sound it makes. What I don't understand is why I have it. My room has wall to wall carpet two bass traps in corners behind my speakers and 6 acoustic panels on the walls. So why do I still have what seems to me a very pronounced ringing. Doesn't this really detract from sound quality? Is there anything I can do that doesn't require me putting foam around my ceiling in the corners? Also would this cause the auto setup to be incorrect with its settings?
