System: HP s5220y -- Pentium Dual-Core CPU E5300 @ 2.60 GHz with 4 GB of memory
Suddenly (and quite recently) AudioEndpointBuilder has become annoyingly intrusive. Task Manager shows about 50% CPU usage, very frequently and often for minutes at a time. Lately this has been happening so often that it is seriously impacting my ability to get anything done.
I wonder what it's looking for; I have no audio devices installed except the original-equipment speakers.
Any ideas? Especially, any idea how to make the service behave reasonably?

Thanks for trying, but I can't find any sign of any ATI devices in my system.
(Maybe they aren't there, or maybe I just don't know how to find them.)

You could restore with a previous system point to check the result.
If the issue persists, I suggest you troubleshoot this issue with resource monitor tool which is built in Windows 7.
(Click start menu, type “resource monitor” or “Resmon.exe” (without the quotes),right-click and run as administrator.)
I would like to share the following articles with you.
How to troubleshoot high CPU in the System process
Hope that helps.

First I disabled the "AgereModemAudio" service. Then I shut down the system to let it cool overnight, rather than leaving it in sleep mode as I usually do, just in case there might be some heat-related hardware complications. Finally I updated the "Realtek High Definition audio" driver.
All of this (or some part of it) seems to have solved the problem. I suppose it's too early to be sure whether the solution is permanent or not, but at least for now I'm very pleased with the result.
Thanks for your help!
