Are you sure that wriiting a config file caused buzzing? Normally it is due to a loose connection of KA/KB or mic/voice or wires running too close to mains, not using twisted pairs etc
Try connecting the DM02 and speaker direct to Comfort using a shoirt cable Does buzzing still happen?

Make sure the firmware is at latest version currently 5.183 see http://www.comfortforums.com/forum68/1866.html
Old versions < 5.145 intercom performance is not so good
Use the default tuning parameters  in Comfigurator 3.1.9, Open new file and do  a selective write to Comfort for Tuning parameters. It can make a world of difference
